4-Aminobutyrate aminotransferase reaction of sulfhydryl residues connected with catalytic activity.
4-Aminobutyrate aminotransferase is inactivated by preincubation with N-(1-pyrene)maleimide (mixing molar ratio 10:1) at pH 7. The reaction with N-(1-pyrene)maleimide was monitored by fluorescence spectroscopy and the degree of labeling of the enzyme determined by absorption spectroscopy. The blocking of 2 cysteinyl residues/enzyme dimer is needed for inactivation of the aminotransferase. The t...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولRole of 4-aminobutyrate aminotransferase in the arginine metabolism of Pseudomonas aeruginosa.
4-Aminobutyrate aminotransferase (GABAT) from Pseudomonas aeruginosa was purified 64-fold to apparent electrophoretic homogeneity from cells grown with 4-aminobutyrate as the only source of carbon and nitrogen. Purified GABAT catalyzed the transamination of 4-aminobutyrate, N2-acetyl-L-ornithine, L-ornithine, putrescine, L-lysine, and cadaverine with 2-oxoglutarate (listed in order of decreasin...
متن کاملThimerosal decreases TRPV1 activity by oxidation of extracellular sulfhydryl residues.
TRPV1, a receptor for capsaicin, plays a key role in mediating thermal and inflammatory pain. Because the modulation of ion channels by the cellular redox state is a significant determinant of channel function, we investigated the effects of sulfhydryl modification on the activity of TRPV1. Thimerosal, which oxidizes sulfhydryls, blocked the capsaicin-activated inward current (I(cap)) in cultur...
متن کاملPerphenazine 4-aminobutyrate Mesylate
Schizophrenia is a lifelong disorder characterized by bizarre delusions, lack of motivation, reduction in spontaneous speech, social withdrawal and some affective symptoms. Perphenazine 4-aminobutyrate mesylate (CYP-1020) is a novel, mutual prodrug ester of GABA and perphenazine that exhibits potent dopamine D2 receptor antagonist and GABAA receptor agonist activity. In relevant animal models, ...
