Crystal structure of Staphylococcus aureus Cystathionine gamma-lyase, Holoenzyme dimer

Released:

Function and Biology Details

Reactions catalysed:
O(4)-succinyl-L-homoserine + L-cysteine = L-cystathionine + succinate
(1a) L-cystathionine = L-cysteine + 2-aminobut-2-enoate
L-cystathionine + H(2)O = L-homocysteine + NH(3) + pyruvate
