MsrA and MsrB are enzymes that can both reduce the S- and R-stereoisomers of (peptidyl-) methionine sulfoxide. The exact nature of the accompanying thioredoxin is not settled, but it is predicted to be TrxA. The whole methionine-MsrA/B-thioredoxin-and-reductase system is an important part of NO detoxification in Mtb (St John et al. 2001, Lee et al. 2009).
