It has been suggested that protein modifications by malondialdehyde (MDA), a major product of lipid peroxidation, contribute to the fluorescence formation of lipofuscin. Although early studies proposed an aminoenimine structure (RNHCH=CHCH=NR) formed from MDA...

The glycation of proteins by glucose has been linked to the development of diabetic complications and other diseases. Early glycation is thought to involve the reaction of glucose with N-terminal and lysyl side chain amino groups to form Schiff's base and fru...

A solid-state and solution analysis of the homo-oligopeptides from epsilon-tert.-butyloxycarbonyl-L-lysine with p-oxymethylbenzylcholestan-3 beta-yl succinate as C-terminal group, using infrared absorption and circular dichroism, is described. The occurrence ...

Proteins are subject of posttranslational modification by sugars and their degradation products in vivo. The process is often referred as glycation. L-Dehydroascorbic acid (DHA), an oxidation product of L-ascorbic acid (vitamin C), is known as a potent glycat...

Tissue transglutaminase (TGase) is a Ca(2+)-dependent enzyme that catalyzes cross-linking of intracellular proteins through a mechanism that involves isopeptide bond formation between Gln and Lys residues. In addition to its transamidation activity, TGase can...
