we have investigated the preventive effects of oral administration of isolated e.coli ghttam'tc acid decarboxylase (gad) in animal models. based on our results, the blood glucose levels were reduced by oral administration of gad to rats 14 days before intraperitoneal injections of streptozocin (40 mg/kg on five consecutive days). on the other hand, oral administration of gad to rats before stre...

Spermidine and cadaverine were found to be constituents of the cell wall peptidoglycan of Anaerovibrio lipolytica, a strictly anaerobic bacterium. The peptidoglycan was degraded with the N-acetylmuramyl-L-alanine amidase and endopeptidase into two peptide fragments, peptide I and peptide II, at a molar ratio of 4:1. Peptides I and II were identified as L-alanine-D-glutamic acid(alphacadaverine)...

background: l-glutamic acid is one of the major amino acids that is present in a wide variety of foods. it is mainly used as a food additive and flavor enhancer in the form of sodium salt. corynebacterium glutamicum (c. glutamicum) is one of the major organisms widely used for glutamic acid production. methods: the study was dealing with immobilization of c. glutamicum and mixed culture of c. g...

Equilibria of the reaction of molybdenum(VI) with L-aspartic acid (Asp) and L- Glutamic acid(Glu) have been studied by spectrophotometric measurements in mixed solvent systems at an ionicstrength of 0.2 mol/dm3 sodium perchlorate, employed (15, 20, 25, 30± 0.1°C) at pH ranges of 3.2to 5.5 with a high ratio of ligand to metal. The stability constants of the complexes and theresulting free energy...

A cell envelope particulate fraction from an encapsulated strain of Bacillus licheniformis ATCC 9945A contains a polygldamyl synthetase which catalyzes the polymerization of L-glutamic acid to form a high molecular weight polymer of y-D-glutamic acid. The reaction, which is specific for L-glutamic acid, requires ATP and Mg2f ion and is stimulated by K+ ion and dithiothreitol. A nearly Z-fold in...
