The Inhibition of Fumarase and Malic Dehydrogenase
The competitive inhibition of malic dehydrogenase by /3-fluorooxaloacetate has been reported by Kun et al. (1). In addition to its inhibitory effect, /3-fluoro-oxaloacetate also oxidized reduced diphosphopyridine nucleotide enzymatically, but at a rate only 0.02% that of oxaloacetate. It was also shown (2) that fi-fluorooxaloacetate was a competitive inhibitor of glutamic-aspartic transaminase,...
متن کاملInhibition of 2,4-dichlorophenoxyacetic Acid-stimulated elongation of pea stem segments by a xyloglucan oligosaccharide.
Xyloglucan, isolated from the soluble extracellular polysaccharides of suspension-cultured sycamore (Acer pseudoplatanus) cells, was digested with an endo-beta-1,4-glucanase purified from the culture fluid of Trichoderma viride. A nonasaccharide-rich Bio-Gel P-2 fraction of this digest inhibited 2,4-dichlorophenoxyacetic-acid-stimulated elongation of etiolated pea stem segments. The inhibitory ...
متن کاملContamination of malic dehydrogenase with apotransaminase.
TRANSAMINASES are among the enzyme requiring pyridoxal-5 phosphate as a co-factor (1). Tn the course of studies on the presence of the apoenzyme of glutamic oxaloacetic transaminase (GOT) in the serum, it was found that the malic dehydrogenase preparations, which are used in the Karmen (2) transaminase assay system, had variable amounts of apotransaminase. The studies reported below present the...

متن کاملKinetics of Sphalerite Leaching by Sodium Nitrate in Sulfuric Acid
In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...
