Cysteine sulfide β Cystationine beta lyase (CBL EC4.4.1.8) belongs to the class of lyases that catalyze cysteine sulfide β After the removal of pyruvate and NH3, homocysteine is generated through cleavage. This enzyme is used in enzyme cycle methodology for the detection of homocysteine in the blood.
