5-Histidylcysteine sulfoxide synthase
(Redirected from 5-histidylcysteine sulfoxide synthase)
5-Histidylcysteine sulfoxide synthase is the first enzyme in the biosynthesis of ovothiol, catalyzing the oxidative addition of cysteine to histidine, forming 5-histidylcysteine sulfoxide.[1] The enzyme is found in Trypanosomes, where it additionally has a SAM dependent methyl transferase, which adds a methyl group to N1.
