Aldehyde dehydrogenases (ALDH) belong to the oxidoreductase family, which catalyze the conversion of aldehydes to their corresponding acids. As a group of NAD(P)+-dependent enzymes, aldehyde dehydrogenases (ALDHs) are involved in oxidation of a large number of aldehydes into their weak carboxylic acids (Moreb, et al., 2012). ALDH is found in every subcellular region such as cytosol, endoplasmic...

The regulation of a number of sugar dehydrogenases in a pseudomonad has been described previously as being loosely coordinated (1). Most enzymes of bacteria which are regulated in concert have been found to function as parts of a common metabolic pathway, such as those involved in the biosynthesis of histidine and arginine (2, 3), or those involved in galactose and lactose metabolism (4, 5). Th...

1. Lipoyl dehydrogenase (NADH: lipoamide oxidoreductase, ED 1.6.4.3) and two asparagusate dehydrogenases from asparagus mitochondria were purified by a series of steps, freezing and thawing, sodium dodecylsulfate extraction, and chromatography on Sephadex G-200 and DEAE-cellulose. 2. Lipoyl dehydrogenase was highly specific for alpha-lipoic acid, which could not be replaced at all by asparagus...

Brief formalin fixation in the cold prior to histochemical assay of rat liver and pancreas for various dehydrogenases has been used successfully to circumvent the structural damage and enzymatic loss to which mitochondria of frozen sections would otherwise be subject. To obtain an optimal result a single set of conditions has been devised, including fixation prior to freezing of minute (finely ...

Dowler, William M. (University of Illinois, Urbana), Paul D. Shaw, and David Gottlieb. Terminal oxidation in cell-free extracts of fungi. J. Bacteriol. 86:9-17. 1963.-The terminal respiration in cell-free extracts of ten representative fungi is mediated by an electron transport system similar to that observed in animal tissue. Reduced nicotinamide adenine dinucleotide (NADH) and succinic cytoch...

The present study was performed for the ecotoxicity assessment of bismuth (Bi) effect on biological indicators soil condition: total number bacteria, catalase activity, dehydrogenases activity and germination Radish seeds length roots. Three types with significantly different resistance ability to heavy metal pollution were studied: Haplic Chernozems Calcic, Arenosols Eutric Cambisols Eutric.So...

The geometric specificity of three different alcohol dehydrogenases (alcohol:NAD+ oxidoreductase, EC 1.1.1.1) (from yeast, from horse liver, and from Leuconostoc mesenteroides) in the reduction of trans- and cis-cinnamaldehydes has been investigated. All three enzymes display a remarkable trans specificity: they react with the trans isomer 7 to 647 times faster than with its cis counterpart. Ex...
