EC 3.5.4.3 is an enzyme commission number that refers to the enzyme "L-asparaginase," which is involved in the hydrolysis of L-asparagine to L-aspartate and ammonia. This enzyme plays a crucial role in the metabolism of amino acids and is particularly important in the treatment of certain types of leukemia and lymphoma, as it can deplete the levels of L-asparagine, which is essential for the growth of certain cancer cells. L-asparaginase is also used in the production of aspartame, a low-calorie sweetener. The enzyme is found in various organisms, including bacteria, fungi, and plants, and its activity can be inhibited by certain compounds, which is significant for understanding its regulation and potential therapeutic applications.
The CAS Registry Mumber 9033-16-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 3 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9033-16: (6*9)+(5*0)+(4*3)+(3*3)+(2*1)+(1*6)=83 83 % 10 = 3 So 9033-16-3 is a valid CAS Registry Number.
