Fig. 2From: Isoaspartic acid is present at specific sites in myelin basic protein from multiple sclerosis patients: could this represent a trigger for disease onset?A major source of degradation of long-lived proteins is racemisation. This spontaneous process affects aspartate, asparagine and serine residues in unstructured regions of these proteins. Illustrated is the mechanism responsible for Asp and Asn racemizationBack to article page
