Sulfate permease is a type of membrane protein that functions as a transporter, specifically facilitating the movement of sulfate ions (SO4^2-) across cell membranes. These proteins are crucial in various biological processes, including the synthesis of essential biomolecules such as amino acids, nucleic acids, and certain coenzymes. They are found in both prokaryotic and eukaryotic organisms and play a significant role in sulfate uptake and assimilation. Sulfate permeases are selective for sulfate ions and can be regulated by various factors, such as the presence of other anions and the cell's metabolic needs. Their activity is vital for maintaining cellular homeostasis and ensuring the availability of sulfate for critical biological functions.
The CAS Registry Mumber 9055-26-9 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, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9055-26: (6*9)+(5*0)+(4*5)+(3*5)+(2*2)+(1*6)=99 99 % 10 = 9 So 9055-26-9 is a valid CAS Registry Number.
