posttranslational modification

the further differentiation protein undergoes after translation by, for example, methylation, phosphorylation, glycosylation, sulfation, disulfide bonding, and other processes.

posttranslational modification

The alteration of a protein, e.g., by phosphorylation or by the addition of carbohydrates to its structure. This process changes both the structure of proteins and their functions in biochemical reactions.

Bhattacharya said their findings add to a growing realization that posttranslational modifications such as deimination regulate local dendritic protein synthesis.
It has the limitations of being transparent to proteins that don't contain cysteine (around 8% of all proteins) and that posttranslational modifications are likely to be missed.
