Sulfate uptake and assimilation
S-Methylcysteine
An alternative pathway of synthesis of S-methylcysteine involves reaction of O-acetylserine with methane thiol (Giovanelli et al, 1980):
OAS + CH3SH ---> S-methylcysteine + acetate
This reaction is analogous to that catalyzed by cysteine synthase:
OAS + H2S ---> cysteine + acetate
