mycoredoxin-1 + H2O2 | mycoredoxin-1 (MtMrx1), a glutaredoxin-like, mycothiol-dependent oxidoreductase, directly reduces the oxidized form of the enzyme (MtAhpE), through a protein mixed disulfide with the N-terminal cysteine of MtMrx1 and the sulfenic acid derivative of the peroxidatic cysteine of MtAhpE. This disulfide is then reduced by the C-terminal cysteine in MtMrx1. Accordingly, MtAhpE catalyzes the oxidation of wild-type MtMrx1 by hydrogen peroxide but not of MtMrx1 lacking the C-terminal cysteine, confirming a dithiolic mechanism | Mycobacterium tuberculosis | mycoredoxin-1 disulfide + 2 H2O | - |
