MULTISPECIES: type II toxin-antitoxin system Phd/YefM family antitoxin [Lactobacillaceae]

Protein Classification

type II toxin-antitoxin system Phd/YefM family antitoxin( domain architecture ID 10005482)

type II toxin-antitoxin (TA) system Phd/YefM family antitoxin is the antitoxin component of a TA module that binds to its cognate toxin and neutralizes its mRNA interferase activity; similar to Escherichia virus P1 antitoxin phd (prevent-host-death)

 8-52 1.13e-05

Antitoxin Phd_YefM, type II toxin-antitoxin system; Members of this family act as antitoxins in type II toxin-antitoxin systems. When bound to their toxin partners, they can bind DNA via the N-terminus and repress the expression of operons containing genes encoding the toxin and the antitoxin. This domain complexes with Txe toxins containing pfam06769, Fic/DOC toxins containing pfam02661 and YafO toxins containing pfam13957.

 4-50 4.82e-03

prevent-host-death family protein; This model recognizes a region of about 55 amino acids toward the N-terminal end of bacterial proteins of about 85 amino acids in length. The best-characterized member is prevent-host-death (phd) of bacteriophage P1, the antidote partner of death-on-curing (doc) (TIGR01550) in an addiction module. Addiction modules prevent plasmid curing by killing the host cell as the longer-lived killing protein persists while the gene for the shorter-lived antidote is lost. Note, however, that relatively few members of this family appear to be plasmid or phage-encoded. Also, there is little overlap, except for phage P1 itself, of species with this family and with the doc family.
