Which of the following is a reversible post-translational covalent modification?

Question

Quizplus · Accepted Answer

Phosphorylation and acetylation are reversible post-translational modifications. Phosphorylation involves the addition of a phosphate group, typically to serine, threonine, or tyrosine residues, and can be reversed by phosphatases. Acetylation involves the addition of an acetyl group, often to lysine residues, and can be reversed by deacetylases. Disulfide bond formation, on the other hand, involves the formation of a covalent bond between two cysteine residues and is not typically classified as reversible under physiological conditions without the aid of specific enzymes.
