Environmental conditions, e.g. pH and the presence of Fe are well known factors that influence the product profile of the myrosinase catalysed hydrolysis of glucosinolates. Depending on the plant genera, the species and tissue of origin myrosinase isoenzymes (thioglucohydrolase EC 3.2.1.147) have different characteristics in terms of MW, subunit composition and pI. However, the influence of the...
Over a five-month period, using data from patients in whom alkaline phosphatase (ALP) isoenzyme studies were requested routinely, we compared actual clinical diagnoses with the predicted diagnoses based on the results of electrophoretic separation of ALP isoenzymes on cellulose acetate before and after heat treatment and on elevated enzymatic activity of gamma glutamyl transferase (GGT) and ala...
The mix of cellular pumps, channels, transporters, and isoenzymes is genetically inherited. However, the environment has the ability to impact the cellular pumps, channels, transporters, and isoenzymes to some degree. Cellular pumps, channels, transporters and isoenzymes help control cellular pH and vice versa. Therefore possibly the pH in the nervous system is more variable than previously bel...
Total lactate dehydrogenase (LD, EC 1.1.1.27) and LD isoenzymes were determined in serum of 170 patients with metastatic liver disease, 35 of whom had multiple metastatic sites. Overall, values of LD were above normal for 78% of the 170 patients. Half of the patients had an isomorphic pattern of LD isoenzymes (i.e., relative increase in all five isoenzymes); the other half had an increased LD-4...
Laccase is one of the ligninolytic enzymes found in liquid cultures of the fungus Ceriporiopsis subvermispora in defined medium. As an approach to a clarification of the role of laccases during the attack on lignin by the fungus, the enzyme has been characterized further. The levels of this phenol oxidase increase 2-fold in the presence of p-anisidine and are severely affected when addition of ...
Alkaline phosphatises (ALP) are a group of isoenzymes produced by liver (isoenzymes ALP1-1), bones (isoenzymes ALP2), kidneys, small intestine and placenta (isoenzymes ALP-3) [1,2]. The serum ALP level represents the total amounts of isoenzymes that are released from the tissues into the bloodstream. Placenta ALP is physiologically produced by placenta at the brush border membranes of the syncy...
Previously we have purified and characterized a major glutathione S-transferase (GST) activity, GST-4a, from the Thai mosquito Anopheles dirus B, a model mosquito for study of anopheline malaria vectors [Prapanthadara, L. Koottathep, S., Promtet, N., Hemingway, J. and Ketterman, A.J. (1996) Insect Biochem. Mol. Biol. 26:3, 277-285]. In this report we have purified an isoenzyme, GST-4c, which ha...
The effect of dietary and hormonal variations on the specific activities of hexokinase isoenzymes, N-acetylglucosamine kinase and pyruvate kinase isoenzymes in parenchymal and non-parenchymal liver cells was studied. Hexokinase D was markedly decreased in hepatocytes from animals fasted or fed on the carbohydrate-free diet as well as from diabetic rats, attaining a constant low level of about 1...
Applying recent developments in protein purification techniques, a number of lipoxygenase isoenzymes have been isolated in satisfactory quantities for a detailed physical and structural characterization. Four seed isoenzymes from two soybean cultivars have been studied by peptide mapping, free thiol and iron content determinations, and C-terminal analysis as well as by uv-visible absorption and...
