Mycothiol-dependent nitroreductase Rv2466c is a key oxidoreductase that mediates the reductive activation of TP053, a thienopyrimidine derivative that kills replicating and non-replicating Mycobacterium tuberculosis. This enzyme transforms nitro-containing compounds to their corresponding amine and uses as a cofactor, a low molecular weight sugar thiol, mycothiol. The Rv2466c structure adopts a thioredoxin-like fold but it forms an unique homodimer in which the C-terminal beta-strand is swapped between the thioredoxin domains of each subunit [1-3]. Rv2466c undergoes significant conformational changes upon formation of its oxidized state [2].
