RNA-dependent RNA polymerase (RdRp) in the Aphthovirus genus of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the RdRp of RNA viruses belonging to the Aphthovirus genus within the family Picornaviridae, order Picornavirales. Member viruses have a (+)ssRNA genome. This genus includes species such as bovine rhinitis A virus, bovine rhinitis B virus, equine rhinitis A virus, and food-and-mouth disease virus (FMDV). Aphthoviruses primarily infect via the upper respiratory tract. FMDV infects mainly cloven-hoofed animals, but has been isolated from at least 70 species of mammals. Aphthoviruses are non-enveloped and have an icosahedral capsid with a diameter of around 27 to 30 nm. The assembled viral capsid contains a single copy of the RNA genome and 60 copies of the four viral capsid proteins VP1, VP2, VP3, and VP4. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. : Pssm-ID: 438060 Cd Length: 458 Bit Score: 940.53 E-value: 0e+00

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Picornaviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Picornaviridae, order Picornavirales. The Picornaviridae family consists of small, icosahedral viruses with (+)ssRNA genomes. Characteristic features of all members of the family Picornaviridae are three capsid proteins with beta-barrel folding, polyprotein processing by virus-encoded cysteine proteinase(s), and replication by an RdRp with a YGDD sequence motif. The family Picornaviridae comprises 68 genera containing 158 species, but many viruses are presently awaiting classification. The established genera of the family include: Aphthovirus, Avisivirus, Crohivirus, Enterovirus, Teschovirus, Cardiovirus, Erbovirus, Kobuvirus, Hepatovirus, Parechovirus, Aquamavirus, Avihepatovirus, Avisivirus, Cosavirus, Dicipivirus, Fipivirus, Gallivirus, Hunnivirus, Kunsagivirus, Limnipivirus, Megrivirus, Mischivirus, Mosavirus, Oscivirus, Pasivirus, Passerivirus, Rabovirus, Rosavirus, Sakobuvirus, Salivirus, Sapelovirus, Senecavirus, Sicinivirus, and Tremovirus. The Picornaviridae contains many important human and animal pathogens including enteroviruses (such as poliovirus, enterovirus, coxsackievirus, and rhinovirus), cardioviruses (such as encephalomyocarditis virus and Theiler's virus), hepatitis A virus and foot-and-mouth disease virus. Infection with various picornaviruses may cause encephalitis, febrile rash illnesses (hand-foot-and-mouth disease), aseptic meningitis, hepatitis, conjunctivitis, herpangina, myositis and myocarditis, and the common cold. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides.

The Mischivirus contains viruses with (+)ssRNA genomes that produce nonenveloped virions. Mischivirus is a picornavirus genus containing five species Mischivirus A, Mischivirus B, Mischivirus C, Mischivirus D and the proposed Mischivirus E. The name is derived from the name originally given to the virus, Miniopterus schreibersii picornavirus, which was found in the common bent-wing bat (aka Schreiber's long-fingered bat or Schreiber's bat) in China and is most closely related to the cardioviruses. RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions. The initiation of synthesis occurs at the 3'-end of the template in a VPg-dependent manner, and proceeds in the direction of 5'-3'. The active sites of RdRps are highly conserved in different species of picornaviruses. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb.

The Cosavirus contains viruses with (+)ssRNA genomes that produce nonenveloped virions. This genus consists of five species Cosavirus A, Cosavirus B, Cosavirus D, Cosavirus E and Cosavirus F. The candidate species, Cosavirus C, remains unclassified due to a lack of full genome sequence data. Cosaviruses (formerly called Dekaviruses) have been identified in the stools of south Asian children. Cosaviruses are most closely related to members of the Cardiovirus and Senecavirus genera, but they lack a leader polypeptide. The name Cosavirus stands for common stool-associated picornavirus. RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions.

Megrivirus A is comprised of turkey hepatitis virus 1 (THV-1), duck megrivirus and goose megrivirus 1. Megrivirus B contains the mesiviruses. Megrivirus D contains harrier picornavirus 1 (HaPV-1). Megrivirus E was found in an Adelie penguin. RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions. The initiation of synthesis occurs at the 3'-end of the template in a VPg-dependent manner, and proceeds in the direction of 5'-3'. The active sites of RdRps are highly conserved in different species of picornaviruses. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. Pssm-ID: 438073 Cd Length: 432 Bit Score: 277.49 E-value: 5.56e-82

conserved catalytic core domain of RNA-dependent RNA polymerase (RdRp) from the positive-sense single-stranded RNA [(+)ssRNA] viruses and closely related viruses; This family contains the catalytic core domain of RdRp of RNA viruses which belong to Group IV of the Baltimore classification system, and are a group of related viruses that have positive-sense (+), single-stranded (ss) genomes made of ribonucleic acid (RNA). RdRp (also known as RNA replicase) catalyzes the replication of RNA from an RNA template; specifically, it catalyzes the synthesis of the RNA strand complementary to a given RNA template. The Baltimore Classification is divided into 7 classes, 3 of which include RNA viruses: Group IV (+) RNA viruses, Group III double-stranded (ds) RNA viruses, and Group V negative-sense (-) RNA viruses. Baltimore groups of viruses differ with respect to the nature of their genome (i.e., the nucleic acid form that is packaged into virions) and correspond to distinct strategies of genome replication and expression. (+) viral RNA is similar to mRNA and thus can be immediately translated by the host cell. (+)ssRNA viruses can also produce (+) copies of the genome from (-) strands of an intermediate dsRNA genome. This acts as both a transcription and a replication process since the replicated RNA is also mRNA. RdRps belong to the expansive class of polymerases containing so-called palm catalytic domains along with the accessory fingers and thumb domains. All RdRps also have six conserved structural motifs (A-F), located in its majority in the palm subdomain (A-E motifs) and the F motif is located on the finger subdomain. All these motifs have been shown to be implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. In addition to Group IV viruses, this model also includes Picobirnaviruses (PBVs), members of the family Picobirnaviridae of dsRNA viruses (Baltimore classification Group III), which are bi-segmented dsRNA viruses. The phylogenetic tree of the RdRps of RNA viruses (realm Riboviria) showed that picobirnaviruses are embedded in the branch of diverse (+)RNA viruses; sometimes they are collectively referred to as the picornavirus supergroup. RdRps of members of the family Permutatetraviridae, a distinct group of RNA viruses that encompass a circular permutation within the RdRp palm domain, are not included in this model.

Iflaviridae is a family of small non-enveloped viruses with (+)ssRNA genomes of approximately 9-11 kilobases in length encoding a single polyprotein. All members infect arthropod hosts with the majority infecting insects. Beneficial and pest insects serve as hosts and infections can be symptomless (Nilaparvata lugens honeydew virus 1), cause developmental abnormalities (deformed wing virus, Varroa destructor virus 1, sacbrood virus), behavioral changes (deformed wing virus, Varroa destructor virus 1, slow bee paralysis virus, sacbrood virus) and premature mortality (deformed wing virus, Varroa destructor virus 1, slow bee paralysis virus, infectious flacherie virus, sacbrood virus). RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions. The initiation of synthesis occurs at the 3'-end of the template in a VPg-dependent manner and proceeds in the direction of 5'-3'.

Picobirnaviridae is a family of viruses with bi-segmented (rarely unsegmented) double-stranded RNA (dsRNA) genomes comprising about 4.4 kbp in total, with small, non-enveloped spherical virions. The family includes one genus (Picobirnavirus) grouping three genetic clusters with high sequence variability, two defined by viruses infecting vertebrates and a third with viruses found in invertebrates. Picobirnaviruses have been identified in feces of humans, rabbits, and a variety of other species of mammals, reptiles, birds, and invertebrates. The pathogenicity of picobirnaviruses has not been established; studies conducted with immunocompromised persons suggest that they are opportunistic pathogens that may cause diarrhea. A published phylogenetic tree constructed for RdRps of RNA viruses in the realm Riboviria, showed that picobirnaviruses are embedded in the branch of diverse (+)RNA viruses; sometimes they are collectively referred to as the picornavirus supergroup.

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the positive-sense single-stranded RNA [(+)ssRNA] picorna-like virus Ectropis obliqua, and related viruses; This group contains the catalytic core domain of RdRp of Ectropis obliqua picorna-like virus (EoPV), and related viruses. EoPV is an insect (+)ssRNA virus that causes a lethal granulosis infection of larvae of the tea looper (Ectropis obliqua), and related insect-infecting iflaviruses. Ectropis obliqua, a species of moth, is one of the most destructive pest insects on tea plants throughout growing areas of this crop in southern China. The EoPV genome contains a single large ORF encoding the capsid proteins at the 5' terminus of the genome with the non-structural proteins at the 3' end of the genome. This organization is similar to typical mammalian picornaviruses. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. Pssm-ID: 438021 Cd Length: 239 Bit Score: 47.20 E-value: 5.38e-05

catalytic core domain of RNA-dependent RNA polymerase (RdRp) chronic bee paralysis virus (CBPV) and related positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of the chronic bee paralysis virus (CBPV) and related (+)ssRNA viruses. The CBPV is the causative agent of severe, usually fatal, paralysis in adult honey bees. CBPV has not been assigned to any group or class of viruses because it has a unique genome organization and virion morphology. However, analyses of the nucleic acid sequence showed similarities between the RdRp of CBPV and the RdRps of Tombusviruses, Nodaviruses, Lake Sinai virus 1 and 2 as well as the Anopheline associated C virus (AACV). CBPV was one of the first viruses in honey bees to be described and isolated as it causes characteristic signs of disease in adult honey bees. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. Pssm-ID: 438024 Cd Length: 229 Bit Score: 44.39 E-value: 4.06e-04

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Nodaviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Nodaviridae, order Nodamuvirales. The family name Nodaviridae, derives from the Japanese village of Nodamura where Nodamura virus was first isolated from Culex tritaeniorhynchus mosquitoes. Virions are non-enveloped and spherical in shape with icosahedral symmetry and diameters ranging from 25 to 33 nm. The members of the two genera in this family infect insects (Alphanodavirus) or fish (Betanodavirus). Alphanodavirus infection results in the stunting, paralysis and death of the insect host. The infection of fish by betanodaviruses such as striped jack nervous necrosis virus or red-spotted grouper nervous necrosis virus causes neural necrosis, encephalopathy or retinopathy and is associated with behavioral abnormalities and high mortality, posing significant problems for marine aquaculture. The genome consists of two molecules of (+)ssRNA: RNA1 and RNA2. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. Pssm-ID: 438023 Cd Length: 236 Bit Score: 44.04 E-value: 5.44e-04

catalytic core domain of RNA-dependent RNA polymerase (RdRp) in the family Solinviviridae of positive-sense single-stranded RNA [(+)ssRNA] viruses, in the order Picornavirales; This group contains the catalytic core domain of RdRp of RNA viruses belonging to the family Solinviviridae, order Picornavirales. Solinviviridae is a family of picorna/calici-like viruses with non-segmented, linear, (+)ssRNA genomes of approximately 10-11 kb. Members of two species within the family infect ants but related unclassified virus sequences derive from a large variety of insects and other arthropods. Phylogenetic analysis of RdRp amino acid sequences shows that members of the two classified solinvivirus species form part of a large and very diverse group of arthropod-infecting viruses within the picorna/calici-like group of viruses. RdRps catalyze RNA template-dependent formation of phosphodiester bonds between ribonucleotides in the presence of divalent metal ions. The initiation of synthesis occurs at the 3'-end of the template in a VPg (viral protein genome-linked)-dependent manner, and proceeds in the direction of 5'-3'. The active sites of RdRps are highly conserved in different species of picornaviruses. The RdRp domain displays a right hand with three functional subdomains, called fingers, palm, and thumb. All RdRps contain conserved polymerase motifs (A-G), located in the palm (A-E motifs) and finger (F-G) subdomains. All these motifs have been implicated in RdRp fidelity such as processes of correct incorporation and reorganization of nucleotides. Pssm-ID: 438049 Cd Length: 323 Bit Score: 43.88 E-value: 8.75e-04
