Reactions
H2O + L-Cysteine = NH3 + Pyruvate + Hydrogen sulfide
H2O + L-Cystathionine = NH3 + L-Cysteine + 2-Oxobutanoate
H2O + L-Cystine = NH3 + Pyruvate + Thiocysteine
H2O + L-Selenomethionine = NH3 + 2-Oxobutanoate + Methaneselenol
H2O + L-Selenocystathionine = NH3 + 2-Oxobutanoate + L-Selenocysteine
L-Cystathionine = L-Cysteine + 2-Aminobut-2-enoate
H2O + 2-Aminobut-2-enoate = NH3 + 2-Oxobutanoate
