A process that modifies proteins by adding a phosphate group, often changing their function.
Glycosylation: The addition of sugar molecules to proteins, which can affect their stability and function.
Proteolysis: The breakdown of proteins into smaller polypeptides or amino acids. This is often used to regulate protein activity or remove damaged proteins.
