Both enzymes utilise dihydroxyacetone phosphate (DHAP) to form an enediol(ate) phosphate intermediate as the first step of their reaction pathways. However, the second catalytic step in the MGS reaction pathway is characterized by the elimination of …

    Jun 25, 1999В В· Methylglyoxal Modification of Protein CHEMICAL AND IMMUNOCHEMICAL CHARACTERIZATION OF METHYLGLYOXAL-ARGININE ADDUCTS* 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-arginine adducts using monoclonal 2XW6: The Crystal Structure of Methylglyoxal Synthase from Thermus sp. GH5 Bound to Phosphate Ion.

    Aug 15, 2001 · Methylglyoxal, a known endogenous and environmental mutagen, is a reactive α-ketoaldehyde that can modify both DNA and proteins. To investigate the possibility that methylglyoxal induces a crosslink between DNA and DNA polymerase, we treated a ‘primed template’ DNA and the exonuclease-deficient Klenow fragment (KF exo–) of DNA polymerase I with methylglyoxal in vitro. methylglyoxal (Q903881) From Wikidata.

    Methylglyoxal (MG) is a specific advanced glycation end products structure that forms on proteins during oxidative stress. Our mouse monoclonal antibody can detect methylglyoxal adducts in Western blot and immunohistochemistry, and our Competitive ELISA kit quantifies MG in a variety of protein samples. 2. Chemical properties of methylglyoxal and glyoxal MGO, a yellow hygroscopic liquid, is known as 2-oxopropanal, pyruvaldehyde, or 2-ketopropionaldehyde. It is present in three rapidlyequilibrium forms in aque ous solution; monohydrate is the highest (71%) followed by dihydrate (28%), and the anhy-drated form is only about 1%.4 Depending on
