Abstract:Spontaneous deamidation of amino acids is a physiologically
important
process, particularly for protein aging and diseases. Despite its
widespread occurrence, the mechanism of glutamine deamidation particularly
within proteins remains poorly understood. We have used a multiscale
computational approach to investigate glutamine deamidation in the
tripeptide Glycine–Glutamine–Glycine (Gly–Gln–Gly)
and γS-Crystallin protein. Specifically, both the 5- and 6-membered
water-assisted deamidation pathways in the tripep… Show more
