Use of p-aminophenyl D and L-lactic acids and p-aminophenyl pyruvic acid as effectors in the affinity chromatography of lactate dehydrogenase. 1979

E Brown, and R Joyeau

p-Aminophenyl pyruvic acid and D-p-amino-phenyllactic acid were immobilized on a new synthetic acrylic carrier bearing acylating N-succinimidyl ester groups. The derivatives obtained were used successfully to purify lactate dehydrogenase (LDH) by affinity chromatography, the elution being carried out by means of NADH or preferably L-phenyllactic acid. Moreover, the specific activity of the LDH contained in a human blood serum was increased 270 times, using L-p-aminophenyllactic acid immobilized on a mixed polyacrylic agarose carrier.

UI MeSH Term Description Entries
D007202 Indicators and Reagents Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.

D007770 L-Lactate Dehydrogenase A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist. Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase
D007773 Lactates Salts or esters of LACTIC ACID containing the general formula CH3CHOHCOOR.
D007778 Lactobacillus A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Lactobacillus species are homofermentative and ferment a broad spectrum of carbohydrates often host-adapted but do not ferment PENTOSES. Most members were previously assigned to the Lactobacillus delbrueckii group. Pathogenicity from this genus is rare.

D010667 Phenylpyruvic Acids A group of compounds that are derivatives of phenylpyruvic acid which has the general formula C6H5CH2COCOOH, and is a metabolite of phenylalanine. (From Dorland, 28th ed) Acids, Phenylpyruvic
D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.
