Reaction

Reaction Comment Organism Reaction ID
peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin presence of at least two binding subsites. The first one, whose contribution is major in the efficiency of the reductase step and in which the epsilon-methyl group of MetSO binds, is the hydrophobic pocket formed by Phe52 and Trp53, the position of the indole ring being stabilized by interactions with His186 and Tyr189. The second subsite composed of Asp129 and Tyr197 contributes to the binding of the main chain of the substrate but to a lesser extent Neisseria meningitidis
