Determination of aspartic and glutamic acids by enzymatic decarboxylation.
Suspensions of Clostridium welchii (strain SR 12) quantitatively decarboxylate the L isomers of aspartic (1) and glutamic acids (2) to ar-alanine and y-aminobutyric acid, respectively. Although a quantitative procedure for the determination of glutamic acid based upon decarboxylation with this organism has been described (3), it has been found that aspartic acid, especially in the presence of c...
متن کاملDeacetylation of N-acetyl-L-glutamic acid by Neurospora crassa.
Photosynthetic bacteria and blue-green algae synthesize ornithine from glutamic acid by a cyclic route in which the intermediate N-acetylglutamic acid is regenerated by a transacetylation reaction; furthermore, in these microorganisms, arginine, which is synthesized from ornithine, is a specific inhibitor of N-acetyl-,y-glutamokinase which phosphorylates N-acetylglutamic acid on its y-carboxyl ...
متن کاملPd-catalyzed decarboxylation of glutamic acid and pyroglutamic acid to bio-based 2-pyrrolidone
In order to recycle nitrogen from nitrogen-rich waste streams, particularly protein waste, we studied the decarboxylation of pyroglutamic acid and glutamic acid in a one-pot reaction to bio-based 2-pyrrolidone. After the screening of a wide range of supported Pd and Pt catalysts, 5 wt% Pd/Al2O3 displayed the highest yield (70%) and selectivity (81%) for the decarboxylation of pyroglutamic acid ...
متن کاملUsefulness of trehalose fermentation and L-glutamic acid decarboxylation for identification of biochemically aberrant Providencia stuartii strains.
A total of 849 Providencia isolates were collected during a 4-year period when an increased incidence of nosocomial Providencia stuartii infection was noted in urologic wards. Of these isolates, 630 were identified as P. stuartii, 206 were identified as Providencia rettgeri, and 1 was identified as Providencia alcalifaciens. Twelve inositol-positive isolates from 10 patients (10 strains) resemb...
متن کاملl-Glutamic acid hydrochloride at 153 K
THE TITLE COMPOUND [SYSTEMATIC NAME: (S)-1,3-dicarboxy-propanaminium chloride], C(5)H(10)NO(4) (+)·Cl(-), has been investigated previously by Dawson [Acta Cryst. (1953). 6, 81-83], with R = 0.106 and without the location of H atoms, and then by Sequeira, Rajagopal & Chidambaram [Acta Cryst. (1972). B28, 2514-2519] using neutron diffraction with R = 0.043. The present determination at 153 K has ...
