Functional information

Function Uniprot Antitoxin component of an atypical, type II toxin-antitoxin chaperone (TAC) module. 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.
Role Unknown
Protein family SinR
Structure (PDB ID) 5MTW
