Term Name:	protein modification process
Synonyms:	cellular protein modification process, process resulting in protein modification, protein modification
Definition:	The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification).
