Cystathionine lyase requires which cofactor ?
Thymine
Riboflavin
Pyridoxine
Niacin
Hydrolytic cleavage (hydrolysis) of cystathionine forms Homoserine plus cysteine.This reaction is catalyzed by the enzyme cystathionine lyase (cystathionase), which requires cofactor pyridoxal phosphate (active form of pyridoxin).
