Tryptophan synthase is a bienzyme complex that plays a crucial role in the biosynthesis of the essential amino acid tryptophan. This enzyme is composed of two protein subunits, alpha and beta, which work together to catalyze a two-step reaction. In the first step, the alpha subunit converts indole-3-glycerol phosphate (IGP) and serine into indole, water, and glyceraldehyde 3-phosphate (G3P). In the second step, the beta subunit combines indole with L-glutamine to form L-tryptophan and L-glutamate. Tryptophan synthase is an important enzyme in the metabolic pathway, as it not only produces tryptophan but also helps regulate the levels of this amino acid in cells. The enzyme's activity is regulated by feedback inhibition, ensuring that tryptophan levels are maintained within a specific range.
The CAS Registry Mumber 9014-52-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 4 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 9014-52: (6*9)+(5*0)+(4*1)+(3*4)+(2*5)+(1*2)=82 82 % 10 = 2 So 9014-52-2 is a valid CAS Registry Number.
