CC   -!- FUNCTION: Toxic component of a type II toxin-antitoxin (TA) system.
CC       Ribosome-independent, sequence-specific endoribonuclease that cleaves
CC       mRNA, thus inhibiting protein synthesis and inducing bacterial stasis.
CC       It cuts between the first and nucleotides of 5'-UACAU-3' in single-
CC       stranded RNA. Neutralized by coexpression with cognate antitoxin MazE.
CC       {ECO:0000250|UniProtKB:A6QIR4}.
CC   -!- SUBUNIT: Forms a complex with MazE which is no longer active as an
CC       endoribonuclease. {ECO:0000250|UniProtKB:A6QIR4}.
CC   -!- SIMILARITY: Belongs to the PemK/MazF family. {ECO:0000305}.
