1.11.1.29 hydrogen sulfide + ROOH - 1.11.1.29 mycoredoxin + ROOH Mycobacteria employ a versatile machinery of the mycothiol-dependent system, containing the proteins mycothiol disulfide reductase, the oxido-reductase Mycoredoxin-1 and the alkyl-hydroperoxide subunit E (AhpE). The mycothiol-dependent protein ensemble regulates the balance of oxidized-reduced mycothiol, to ensure a reductive intracellular environment for optimal functioning of its proteins even upon exposure to oxidative stress. The epitopes of MtMrx-1 and MtAhpE interaction are described 1.11.1.29 mycoredoxin-1 + ROOH - 1.11.1.29 mycoredoxin-1 + ROOH mycoredoxin-1 (MtMrx1) acts in combination with mycothiol and mycothiol disulfide reductase, is a biologically relevant reducing system for MtAhpE 1.11.1.29 mycothiol + ROOH -
