Accumulation of freely extractable glutamic acid by lactic acid bacteria.
Gale (2, 3) initially described the existence in bacteria of a metabolism-dependent process achieving the accumulation of freely extractable amino acids. During the studies described here a number of additional reports have appeared citing examples of amino acid (4, 5), carbohydrate (6), and phosphate (7) accumulations in bacteria. The mechanism of these accumulations is unknown. Christensen et...
متن کاملFormation of Erythroascorbic Acid and 2,3-Enediol Pentonic Acid from L-Ascorbic Acid by Purple Sulfur Bacteria
Phototrophic growth of Chromatium vinosum strain D on pyruvate or malate, and of Thiocapsa roseopersicina strain 631.1 on malate or sulfide as sole electron donors was promotedby 5 m M L-ascorbate, while growth of T. roseopersicina on fructose was inhibited. Slow growth was obtained also with ascorbate alone. In ascorbate-containing cultures the medium developed a yellow to red-brown colour whi...
متن کاملKinetics and mechanism of oxidation of chromium ( III ) - L - glutamic acid complex by periodate Hassan
where k, is the rate constant for the electron transfer process, K1 the equiiibrium constant for dissociation of [Cr(Lh(H20h+l to [Cr(Lh(H20)(0H)] + W, and K5 the pre-equilibrium format ion constant. Values of k2 = 2.93xl0s• K1 = 6.26 x 10--4 mol dmand K5 = 88.4 1 dm mor 1 have been obtained at 30°C and I= 0.2 mol dmThermodynamic activation parameters have been calculated. It is proposed that e...
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 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 ...
