9031-94-1 Usage
Uses
Aminopeptidase I from Streptomyces griseus has been used: to test the biochar exposure effect on the enzyme activity in circular dichroism (CD) spectroscopy studies as a positive control in p-nitroanilide degradation assay
General Description
Aminopeptidase I from Streptomyces griseus is a thermostable enzyme with Glu131 and Tyr246 as key active site residues.
Biochem/physiol Actions
Aminopeptidase I may also be used as a reagent in the assay of endoprotease activities with a synthetic substrate in a two-stage assay. In the first stage, the endoprotease cleaves a peptide, such as Z-Y-X-Leu-p-nitroanilide, with the X, Y, and Z residues being chosen according to the specificity of the endoprotease.
Check Digit Verification of cas no
The CAS Registry Mumber 9031-94-1 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 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9031-94:
(6*9)+(5*0)+(4*3)+(3*1)+(2*9)+(1*4)=91
91 % 10 = 1
So 9031-94-1 is a valid CAS Registry Number.
