MULTISPECIES: type II toxin-antitoxin system PemK/MazF family toxin [Ralstonia]

Protein Classification

type II toxin-antitoxin system PemK/MazF family toxin( domain architecture ID 10493638)

type II toxin-antitoxin (TA) system PemK/MazF family toxin similar to Staphylococcus aureus MazF, a ribosome-independent sequence-specific endoribonuclease that cleaves at 5'-UACAU-3' sequences of RNA and is the toxin component of the MazF-MazE TA module
