CC   -!- FUNCTION: Possibly the antitoxin component of a type II toxin-antitoxin
CC       (TA) system. Its cognate toxin is VapC5 (Potential). {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the UPF0165 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAB90918.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
