Reactions
H2O + O-Succinyl-L-homoserine = NH3 + Succinate + 2-Oxobutanoate
Hydrogen sulfide + O-Succinyl-L-homoserine = Succinate + L-Homocysteine
Succinate + Cystathionine = L-Cysteine + O-Succinyl-L-homoserine
Thiosulfate + O-Acetyl-L-serine = Acetate + S-Sulfo-L-cysteine
L-Cysteine + O-Acetyl-L-homoserine = Acetate + L-Cystathionine
L-Cysteine + O-Succinyl-L-homoserine = Succinate + L-Cystathionine
L-Selenocysteine + O-Phospho-DL-homoserine = Orthophosphate + L-Selenocystathionine
O-Acetyl-L-homoserine + L-Selenocysteine = Acetate + L-Selenocystathionine
O-Succinyl-L-homoserine + L-Selenocysteine = Succinate + L-Selenocystathionine
