A structural analysis of the catalytic mechanism of methionine sulfoxide reductase A from Neisseria meningitidis.

The methionine sulfoxide reductases (Msrs) are thioredoxin-dependent oxidoreductases that catalyse the reduction of the sulfoxide function of the oxidized methionine residues. These enzymes have been shown to regulate the life span of a wide range of microbial and animal species and to play the role of physiological virulence determinant of some bacterial… (More)
