Affinity Chromatography of Potato Lactate Dehydrogenase

چکیده
NH,CI. None of the adaptations could be attributed to the high-protein diet per se since they were not evident in those rats fed a high-protein diet and given NaHC03 solution to drink. Of particular interest is the increased rate of gluconeogenesis found in kidney slicesfrom rats fed ona high-protein diet. Krebs et al. (1963) have observed an increased rate of renal gluconeogenesis in rats fed on a low-carbohydratediet. However, their lowcarbohydrate diet was enriched in protein and it seems that the increased rate of gluconeogenesis observed may be attributed, at least in part, to the acidogenic effects of the diet.

Characterization of potato (Solanum tuberosum)lactate dehydrogenase isoenzymes by affinity chromatography and hybridization.
The five isoenzymes of potato (Solanum tuberasum) lactate dehydrogenase have been resolved by affinity chromatography. Mixtures of isoenzymes LDH-1 and LDH-5 dissociate and reassociate during freezing and thawing to produce five isoenzymes. These results indicate that potato lactate dehydrogenase isoenzymes are primary isoenzymes of the vertebrate type, which are composed of two subunit types.
متن کاملPurification and properties of hypoxically induced lactate dehydrogenase from barley roots.
Using Affigel Blue and oxamate-agarose affinity chromatography, lactate dehydrogenase (LDH) was purified 2000-fold from hypoxically induced barley roots. Molecular weights of the native and sodium dodecyl sulfate-denatured LDH protein were 157 and 40 kilodaltons, respectively, indicating a tetramer. Purified barley LDH was very similar in size and kinetic properties to potato LDH. However, thei...

A, digestive gland; B, buccal cavity; C, mantle muscle; D, eye; E, brain. The lower margin of the photograph is the position reached by bromophenol blue. The L-LDH was specifically isolated by affinity chromatography before application to the tops of gels (see text). Electrophoresis was carried out in tubes of 7.5% (w/v) polyacrylamide at pH 8.3 according t o the method of Davis 1.51. LDH was v...
متن کاملIsolation of human lactate dehydrogenase isoenzyme X by affinity chromatography.
Human isoenzyme LDH-X (lactate dehydrogenase isoenzyme X) was isolated from seminal fluid of frozen semen samples by affinity chromatography by using oxamate-Sepharose and AMP-Sepharose. In the presence of 1.6 mM-NAD+, isoenzyme LDH-X does not bind to AMP-Sepharose, whereas the other lactate dehydrogenase isoenzymes do. This is the crucial point in the isolation of isoenzyme LDH-X from the othe...
متن کاملThe Determination of Dissociation Constants by Affinity Chromatography on an Immobilized Adenosine Monophosphate Analogue
Within a few years affinity chromatography has become a widely used technique for the separation and purification of enzymes. The development and advantages of general ligands in affinity chromatography have previously been reported (Mosbach et al., 1972; Ohlsson et al., 1972). Thus Sepharose-bound N6-(6-aminohexyl)-AMP has been used for the separation and purification of NAD+-dependent enzymes...
متن کاملPurification of lactate dehydrogenase isoenzyme-5 from human liver.
We present a method for preparing human liver lactate dehydrogenase (L-lactate:NAD+ oxidoreductase; EC 1.1.1.27) isoenzyme-5 by sequential ion-exchange chromatography, general-ligand (AMP analog) affinity chromatography, and preparative isoelectric focusing. The yield ws 40%, with a 493-fold purification. The final specific activity was 458 kU per gram of protein. The preparation contained less...
