Comments In total, there are approximately 300 different PTM that have been reported (Aebersold and Goodlett 2001), affecting protein conformation, stability, localization, binding interactions, and function. The majority of proteins are modified after translation, often at more than one site. In most cases, the sites of modification are not predictable from the amino acid sequence.
