Cysteate synthase (EC 2.5.1.76) is an enzyme characterised from Methanosarcinales with systematic name sulfite:O-phospho-L-serine sulfotransferase (phosphate-hydrolysing, L-cysteate-forming).[1] It catalyses the following chemical reaction which produces L-cysteic acid by reacting phosphoserine with sulfite (H2SO3), giving orthophosphate (Pi) as a byproduct:[2]
This enzyme is a transferase containing pyridoxal-phosphate as a cofactor.[1]
