 30-178 1.23e-83

Hepatitis C virus NS3 protease; Hepatitis C virus NS3 protein is a serine protease which has a trypsin-like fold. The non-structural (NS) protein NS3 is one of the NS proteins involved in replication of the HCV genome. NS2-3 proteinase, a zinc-dependent enzyme, performs a single proteolytic cut to release the N-terminus of NS3. The action of NS3 proteinase (NS3P), which resides in the N-terminal one-third of the NS3 protein, then yields all remaining non-structural proteins. The C-terminal two-thirds of the NS3 protein contain a helicase. The functional relationship between the proteinase and helicase domains is unknown. NS3 has a structural zinc-binding site and requires cofactor NS4A.

 336-457 5.85e-48

P-loop containing Nucleoside Triphosphate Hydrolases; Members of the P-loop NTPase domain superfamily are characterized by a conserved nucleotide phosphate-binding motif, also referred to as the Walker A motif (GxxxxGK[S/T], where x is any residue), and the Walker B motif (hhhh[D/E], where h is a hydrophobic residue). The Walker A and B motifs bind the beta-gamma phosphate moiety of the bound nucleotide (typically ATP or GTP) and the Mg2+ cation, respectively. The P-loop NTPases are involved in diverse cellular functions, and they can be divided into two major structural classes: the KG (kinase-GTPase) class which includes Ras-like GTPases and its circularly permutated YlqF-like; and the ASCE (additional strand catalytic E) class which includes ATPase Binding Cassette (ABC), DExD/H-like helicases, 4Fe-4S iron sulfur cluster binding proteins of NifH family, RecA-like F1-ATPases, and ATPases Associated with a wide variety of Activities (AAA). Also included are a diverse set of nucleotide/nucleoside kinase families.

 197-340 2.60e-51

DEXH-box helicase domain of NS3 protease-helicase; NS3 is a nonstructural multifunctional protein found in pestiviruses that contains an N-terminal protease and a C-terminal helicase. The N-terminal domain is a chymotrypsin-like serine protease, which is responsible for most of the maturation cleavages of the polyprotein precursor in the cytosolic side of the endoplasmic reticulum membrane. The C-terminal domain, about two-thirds of NS3, is a helicase belonging to superfamily 2 (SF2) thought to be important for unwinding highly structured regions of the RNA genome during replication. NS3 plays an essential role in viral polyprotein processing and genome replication. NS3 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

C-terminal helicase domain of viral helicase; Viral helicases in this family here are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

 30-178 1.23e-83

Hepatitis C virus NS3 protease; Hepatitis C virus NS3 protein is a serine protease which has a trypsin-like fold. The non-structural (NS) protein NS3 is one of the NS proteins involved in replication of the HCV genome. NS2-3 proteinase, a zinc-dependent enzyme, performs a single proteolytic cut to release the N-terminus of NS3. The action of NS3 proteinase (NS3P), which resides in the N-terminal one-third of the NS3 protein, then yields all remaining non-structural proteins. The C-terminal two-thirds of the NS3 protein contain a helicase. The functional relationship between the proteinase and helicase domains is unknown. NS3 has a structural zinc-binding site and requires cofactor NS4A.

 197-340 2.60e-51

DEXH-box helicase domain of NS3 protease-helicase; NS3 is a nonstructural multifunctional protein found in pestiviruses that contains an N-terminal protease and a C-terminal helicase. The N-terminal domain is a chymotrypsin-like serine protease, which is responsible for most of the maturation cleavages of the polyprotein precursor in the cytosolic side of the endoplasmic reticulum membrane. The C-terminal domain, about two-thirds of NS3, is a helicase belonging to superfamily 2 (SF2) thought to be important for unwinding highly structured regions of the RNA genome during replication. NS3 plays an essential role in viral polyprotein processing and genome replication. NS3 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

C-terminal helicase domain of viral helicase; Viral helicases in this family here are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.
