BRITE hierarchy
Sysname
O-phospho-L-serine:hydrogen-sulfide 2-amino-2-carboxyethyltransferase
Reaction(IUBMB)
O-phospho-L-serine + hydrogen sulfide = L-cysteine + phosphate [RN:R07274]
Reaction(KEGG)
R07274;
(other) R00897
Show
Substrate
O-phospho-L-serine [CPD:C01005];
hydrogen sulfide [CPD:C00283]
Product
L-cysteine [CPD:C00097];
phosphate [CPD:C00009]
Comment
A pyridoxal-phosphate protein. The enzyme from Aeropyrum pernix acts on both O-phospho-L-serine and O3-acetyl-L-serine, in contrast with EC 2.5.1.47, cysteine synthase, which acts only on O3-acetyl-L-serine.
