BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The stable post-translational modification of proteins by adenylylation or uridylylation was discovered more than four decades ago as a mechanism to regulate the activity of enzymes.

Detailed explanation-2: -Which of the following is not a post-translational modification? Explanation: DNA methylation is not a post-translational modification. It is a biological process in which DNA molecules are methylated. Lipidation, protein phosphorylation, and proteolytic processing are proteolytic processing.

Detailed explanation-3: -Protein acetylation is one of the major post-translational modifications (PTMs) in eukaryotes, in which the acetyl group from acetyl coenzyme A (Ac-CoA) is transferred to a specific site on a polypeptide chain.
