L-Cystathionine-lyase, also known as cystathionine gamma-lyase (CGL), is an enzyme that plays a crucial role in the metabolism of sulfur-containing amino acids. It catalyzes the conversion of L-cystathionine into cysteine, alpha-ketobutyrate, and ammonia. This reaction is essential for the biosynthesis of cysteine, which is a key component of the antioxidant glutathione and a precursor for the synthesis of taurine and coenzyme A. The enzyme is also involved in the transsulfuration pathway, which connects the metabolism of methionine and cysteine. L-Cystathionine-lyase is found in various tissues, including the liver, pancreas, and kidneys, and its activity is regulated by factors such as vitamin B6, which is a cofactor for the enzyme.
The CAS Registry Mumber 9055-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 5 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 9055-05: (6*9)+(5*0)+(4*5)+(3*5)+(2*0)+(1*5)=94 94 % 10 = 4 So 9055-05-4 is a valid CAS Registry Number.
