| Comments |
A pyridoxal-phosphate protein. The enzyme participates in an alternative pathway for L-cysteine biosynthesis that involves a protein-bound thiocarboxylate as the sulfide donor. The enzyme from the bacterium Mycobacterium tuberculosis also has very low activity with O3-acetyl-L-serine (cf. EC 2.5.1.65, O-phosphoserine sulfhydrylase). |
| Cofactor |
pyridoxal 5′-phosphate |
| History |
|
| Reactions |
O-phospho-L-serine + [CysO sulfur-carrier protein]-Gly-NH-CH(2)-C(O)SH = [CysO sulfur-carrier protein]-Gly-NH-CH(2)-C(O)-S-L-cysteine + phosphate. |
