In enzymology, a L-glutamate oxidase (EC 1.4.3.11) is an enzyme that catalyzes the chemical reaction. L-glutamate + O 2 + H 2 O 2-oxoglutarate + NH 3 + H 2 O 2. The 3 substrates of this enzyme are L-glutamate, O 2, and H 2 O, whereas its 3 products are 2-oxoglutarate, NH 3, and H 2 O 2.
In this manner, an amino acid can transfer its amine group to glutamate, after which GDH can then liberate ammonia via oxidative deamination. This is a common pathway during amino acid catabolism. [3] Another enzyme responsible for oxidative deamination is monoamine oxidase, which catalyzes the deamination of monoamines via addition of oxygen ...
In enzymology, a D-glutamate oxidase (EC 1.4.3.7) is an enzyme that catalyzes the chemical reaction D-glutamate + H 2 O + O 2 ⇌ {\displaystyle \rightleftharpoons } 2-oxoglutarate + NH 3 + H 2 O 2 The 3 substrates of this enzyme are D-glutamate , H 2 O , and O 2 , whereas its 3 products are 2-oxoglutarate , NH 3 , and H 2 O 2 .
Dodzin, ME; Vinogradova, KA; Kotova, IB (1998). "[Novel L-glutamate oxidase producing organisms: Streptomyces litmocidini and Streptomyces cremeus]".
The 3 substrates of this enzyme are L-glutamate 5-semialdehyde, phosphate, and NADP +, whereas its 3 products are L-glutamyl 5-phosphate, NADPH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor.
In enzymology, a glutamate synthase (NADPH) (EC 1.4.1.13) is an enzyme that catalyzes the chemical reaction. L-glutamine + 2-oxoglutarate + NADPH + H + 2 L-glutamate + NADP + Thus, the four substrates of this enzyme are L-glutamine, 2-oxoglutarate (α-ketoglutarate), NADPH, and H +, whereas the two products are L-glutamate and NADP +.
An analysis of special elections since November offers some clues about the party's changing fortunes.
The first committed step is the reaction of PRPP, glutamine and water to 5'-phosphoribosylamine (PRA), glutamate, and pyrophosphate - catalyzed by amidophosphoribosyltransferase, which is activated by PRPP and inhibited by AMP, GMP and IMP. PRPP + L-Glutamine + H 2 O → PRA + L-Glutamate + PPi
