UniProtKB - P54950 (SCMK_BACSU)
Protein
N-acetyl-S-(2-succino)cysteine monooxygenase
Gene
scmK
Organism
Bacillus subtilis (strain 168)
Status
Functioni
Probably catalyzes the oxygenation of the 2-position of the succinyl moiety of N-acetyl-S-(2-succino)cysteine, causing a spontaneous elimination reaction of the resulting hemithioketal that generates oxaloacetate and N-acetylcysteine (NAC). Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine.1 Publication

Pathology & Biotechi
Disruption phenotypei
Cells lacking this gene almost lose the ability to grow on 2SC as the sulfur source but are still able to grow on sulfate. Moreover, they show a massive accumulation of N-acetyl-S-(2-succino)cysteine when S2C is added to the medium.1 Publication
