Deamidation site detection software tools | Post-translational modification data analysis

Protein deamidation is a post-translational modification in which the side chain amide group of a glutamine or asparagine residue is transformed into an acidic carboxylate group (Geiger et al., 1987). Non-enzymatic deamidation of asparagine is faster than of glutamine and hence presents higher physiological significance (Robinson et al., 2001), being involved in processes such as apoptosis, brain development and aging (Reissner et al., 2003). Deamidation often (Reissner et al., 2003), but not always, leads to loss of protein function.
