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 glycation agent. A
We have synthesized a hydrophilic crosslinked aminoalkyl polydimethylacrylamide-beaded support upon which peptides have been assembled using standard Fmoc chemistry in automated batch-wise equipment. The resin was prepared by the free radical-initiated co-polymerization of N,N-dimethylacryl-amide, N,N'-bisacrylyl-1,3-diaminopropane and a functional monomer N-methacrylyl-1,3-diaminopropane

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 and the epsilon-amino groups of the
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 bind guanosine 5'-triphosphate (GTP) and does
