9000-83-3 Usage
Uses
ATPase is used to liberate inorganic phosphorus from ATP. ATPase, from porcine cerebral cortex, has been used in inhibition assays of Na/K-ATPase activity .
Biochem/physiol Actions
This membrane enzyme hydrolyzes ATP to ADP and orthophosphate. The hydrolysis is coupled with the exchange of sodium and potassium ions across the plasma membrane. The enzyme is present in almost all tissues of higher organisms, but it is most abundant in the kidney where it reabsorbs sodium ions from the glomerular filtrate. Na+,K+-ATPase is affected by changes in intracellular calcium. It is also sensitive to ouabain and inhibited by vanadate, and (in vitro) by SPAI-1, a peptide isolated from porcine duodenum. It has been reported to be regulated by phosphorylation by protein kinase A (PKA). Bufalin, and other cardiotonic steroids, may inhibit Na+/K+-ATPase activity and induce the differentiation of HL60, U937, and ML1 cells .
Check Digit Verification of cas no
The CAS Registry Mumber 9000-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 9000-83:
(6*9)+(5*0)+(4*0)+(3*0)+(2*8)+(1*3)=73
73 % 10 = 3
So 9000-83-3 is a valid CAS Registry Number.
