CC -!- FUNCTION: Toxic component of a type II toxin-antitoxin (TA) system. An
CC RNase (By similarity). Upon expression in M.smegmatis inhibits
CC translation and colony formation. Its toxic effect on colony formation
CC is neutralized by coexpression with cognate antitoxin VapB22; the
CC effect on translation has not been tested but is probably neutralized
CC also. {ECO:0000255|HAMAP-Rule:MF_00265, ECO:0000269|PubMed:20011113}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00265};
CC -!- SUBCELLULAR LOCATION: Secreted. Note=Following 6 weeks of nutrient
CC starvation. {ECO:0000269|PubMed:23345537}.
CC -!- SIMILARITY: Belongs to the PINc/VapC protein family.
CC {ECO:0000255|HAMAP-Rule:MF_00265}.
