B6db activities: o.succinylhomoserine.sulfhydrylase

Description O-succinylhomoserine sulfhydrylase (2.5.1.-)
Alternative names O-succinylhomoserine(thiol)-lyase (ambiguous).
Catalyzed reaction O-succinyl-L-homoserine + H2S = L-homocysteine + succinate.
Cofactor Pyridoxal-phosphate.
Comments This enzyme is involved in one of the possible pathways for the biosynthesis of methionine.

Cystathionine gamma-synthase (O-succynilhomoserine (thiol)-lyase, EC catalyzes this reaction, too, but the two validated genes encoding O-succinylhomoserine-sulfhydrylase (from Pseudomonas and Rhizobium) are clearly distinct from those encoding EC
