Protein

Cystathionine gamma-synthase

Gene

metB

Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the formation of L-cystathionine from O-succinyl-L-homoserine (OSHS) and L-cysteine, via a gamma-replacement reaction. In the absence of thiol, catalyzes gamma-elimination to form 2-oxobutanoate, succinate and ammonia (By similarity).By similarity

Catalytic activityi

O(4)-succinyl-L-homoserine + L-cysteine = L-cystathionine + succinate.

Cofactori

pyridoxal 5'-phosphateBy similarityNote: Binds 1 pyridoxal phosphate per subunit.By similarity
