WebMar 1, 2024 · It is prudent that process and product development groups share detected Asn deamidation and Asp isomerization sites for particular mAbs with the molecular design and drug discovery groups to ensure sequence liabilities are systematically trended and engineered out of future constructs. This practice helps ensure that only well-behaved ... WebFor example, deamidation of Asn 67 in native ribonuclease A is 30 times slower than the rate of deamidation of this residue in reduced and denatured protein. 97. Glutamine can also undergo deamidation in a reaction analogous to that of Asn, with a six-membered glutarimide intermediate. ... Most of the deamidation products (Asn → Asp, Gln ...
WebDeamidation of asparagine (Asn) and isomerization of aspartic acid (Asp) residues are among the most commonly observed spontaneous post-translational modifications (PTMs) in proteins. WebJan 1, 1999 · Hemoglobin J Sardegna [α50(CD8)His→Asn →Asp] is a human Hb variant in which a posttranslational deamidation process takes place, transforming an Asn to an Asp residue. This variant, particularly widespread in northern Sardinia, has for the first time been characterized at the DNA level (codon 50 C→A) on the selectively amplified α 2 ...
