Function

[VPC11_MYCTU] Toxic component of a type II toxin-antitoxin (TA) system. Acts as an RNase. Upon expression in E.coli and M.smegmatis inhibits translation, cell growth and colony formation. Its toxic effects on cell growth and colony formation are neutralized by coexpression with cognate antitoxin VapB11; the effect on translation has not been tested but is probably also neutralized.^{[1] [2]} [VPB11_MYCTU] Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis neutralizes the effect of cognate toxin VapC11.^{[3] [4] [5]}
