Methylglyoxal modification of protein. Chemical and immunochemical characterization of methylglyoxal-arginine adducts.
Methylglyoxal (MG), an endogenous metabolite that increases in diabetes and is a common intermediate in the Maillard reaction (glycation), reacts with proteins and forms advanced glycation end products. In the present study, we identify a novel MG-arginine adduct and also characterize the structure of a major fluorescent adduct. In addition, we describe the immunochemical study on the MG-argini...
متن کاملDetoxification of Glutaraldehyde Treated Porcine Pericardium Using L-arginine & NABH4
BACKGROUND Calcification is the most frequent cause of clinical failure of bioprosthetic tissues fabricated from GA-fixed porcine valves or bovine pericardium. A multi-factorial approach using different mechanisms was recently developed to reduce the calcification of bioprosthetic tissues. The purpose of the present study was to evaluate the synchronized synergism of using L-arginine and NaBH(4...
متن کاملThe critical role of S-lactoylglutathione formation during methylglyoxal detoxification in Escherichia coli
Survival of exposure to methylglyoxal (MG) in Gram-negative pathogens is largely dependent upon the operation of the glutathione-dependent glyoxalase system, consisting of two enzymes, GlxI (gloA) and GlxII (gloB). In addition, the activation of the KefGB potassium efflux system is maintained closed by glutathione (GSH) and is activated by S-lactoylGSH (SLG), the intermediate formed by GlxI and...
متن کاملGlyoxalase I Gene Deletion Mutants of Leishmania donovani Exhibit Reduced Methylglyoxal Detoxification
BACKGROUND Glyoxalase I is a metalloenzyme of the glyoxalase pathway that plays a central role in eliminating the toxic metabolite methyglyoxal. The protozoan parasite Leishmania donovani possesses a unique trypanothione dependent glyoxalase system. PRINCIPAL FINDINGS Analysis of the L. donovani GLOI sequence predicted a mitochondrial targeting sequence, suggesting that the enzyme is likely t...
متن کاملGlycosylation enhances functional stability of the chemotactic cytokine CCL2.
The human chemokine CCL2 gene was expressed in the yeast P.pastoris and gave rise to a mixture of differently glycosylated recombinant proteins. In comparison to non-glycosylated E.coli-derived CCL2, glycosylated yeast CCL2L was 4-20 times less active in a chemotactic assay in vitro. However, CCL2L could maintain full activity upon prolonged incubation at 37 degrees C, whereas the non-glycosyla...
