“Extractions of Asp, Glu, Ser, Asn , Gly, Gln, Tau, His, Cit, Thr, Pro, Tyr, Val, cystine, Ile, Leu, Trp, Orn, and Lys also were correlated with arteriovenous differences of Met.”
“Only AGEs were generated when heated at 100 °C, Asn and Trp competed with Lys for glucose and methylglyoxal (MGO), and glyoxal (GO) decreased AGE content.”
“The k value of CML, CEL, and acrylamide decreased when heated at 130 °C, whereas that of harmane increased in the Mix/Glu, owing to the competition between Lys and Asn for glucose, GO, and MGO.”
“Substitution of a Lys residue at position 68 with Asn in MUG not only accelerates the removal of uracil from mismatched base pairs but also enables the enzyme to gain catalytic activity on A/U base pairs.”
“The recent discovery of intramolecular isopeptide bonds formed between lysine and asparagine residues in certain bacterial cell-surface proteins represents a new component in nature's toolbox for stabilising proteins.”

“In each of the domains, a covalent isopeptide bond is observed between a lysine and an asparagine , a feature that is believed to be a common stabilization mechanism in Gram-positive surface proteins.”
“Crystallographic studies of pilin subunits have also led to the unexpected discovery of internal isopeptide crosslinks formed between lysine and asparagine residues.”
