CC   -!- FUNCTION: Toxic component of a type II toxin-antitoxin (TA) system. An
CC       RNase. Its toxic effect is neutralized by coexpression with cognate
CC       antitoxin VapB21 (By similarity). {ECO:0000255|HAMAP-Rule:MF_00265}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00265};
CC   -!- SIMILARITY: Belongs to the PINc/VapC protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_00265}.
