UniProtKB accession:  P9WJA7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Antitoxin component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin HigB1. Neutralization of HigB1 toxin in E.coli or M.marinum also requires SecB-like chaperone Rv1957, making this the first toxin-antitoxin chaperone (TAC) system. Antitoxin aggregation and degradation are prevented by the chaperone.
