Production of D-Glutamate from L-Glutamate with Glutamate Racemase and L-Glutamate Oxidase.
We studied production of D-glutamate from L-glutamate using a bioreactor consisting of two columns of sequentially connected immobilized glutamate racemase (EC 5.1.1.3, from Bacillus subtilis IFO 3336) and L-glutamate oxidase (EC 1.4.3.11, from Streptomyces sp. X119-6): L-glutamate was racemized by the glutamate racemase column, and then L-glutamate was oxidized by the L-glutamate oxidase colum...
متن کاملGuanidinium l-glutamate
In the title compound, CH(6)N(3) (+)·C(5)H(8)NO(4) (-), there are two independent cations and two independent anions in the asymmetric unit. In the crystal structure, cations and anions are linked by inter-molecular N-H⋯O hydrogen bonds into a three-dimensional network.
متن کاملInfluence of L-Leucine on Glutamate Dehydrogenase Activity in Isolated Rat Diaphragm 1
Glutamate dehydrogenase (NAD) activity was measured in liver and diaphragm mitochondria from 48 h fasted rats. Kinetic studies were performed with diaphragm enzyme and the effects of L-leu, ADP and L-ala on the K(1)m and V(1)max for NH(4)+, and α-ketoglutarate were evaluated. L-leucine increases by 2-8 fold the V(1)max for all three substrates with no significant changes in the K(1)m. ADP incre...
متن کاملA Plastidial Localization and Origin of l-Glutamate Dehydrogenase in a Soybean Cell Culture.
The subcellular distribution of l-glutamate dehydrogenase (GDH, EC 1.4.1.3.) was studied in SB3 soybean (Glycine max) cells using subcellular fractionation techniques. Compounds that inhibit protein synthesis either on 80s or 70s ribosomes were also used to give a preliminary idea of which subcellular fraction is involved in GDH synthesis. It was found that whereas cycloheximide and puromycin c...
متن کاملRe-investigation of the effects of L-glutamine and L-asparagine on the Neurospora crassa NADP-specific glutamate dehydrogenase.
L-Glutamine, when purified free of traces of NH4+ present in solution, does not act as an alternative substrate to NH4+ for the NADP-specific glutamate dehydrogenase of Neurospora. L-Glutamine interferes with detection of small quantities of NH4+ by Nessler's reagent. L-Asparagine is not an alternative substrate to NH4+ for this enzyme.
