Methylase is a type of enzyme that plays a crucial role in the process of DNA methylation, which is an epigenetic modification. This enzyme catalyzes the transfer of a methyl group from a donor molecule, such as S-adenosylmethionine, to a specific base in the DNA molecule, typically cytosine. This addition of a methyl group can alter the gene expression without changing the DNA sequence itself, leading to various biological effects such as gene silencing, genomic imprinting, and X-chromosome inactivation. Methylase enzymes are essential for maintaining proper gene regulation and play a significant role in development, aging, and disease processes.
The CAS Registry Mumber 9033-25-4 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, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 9033-25: (6*9)+(5*0)+(4*3)+(3*3)+(2*2)+(1*5)=84 84 % 10 = 4 So 9033-25-4 is a valid CAS Registry Number.
