amino acid dehydrogenases (l-amino acid: oxidoreductase deaminating ec 1.4.1.x) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either nad+, nadp+ or fad. these enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...

The activities of six enzymes which take part in the oxidation of valine by Pseudomonas putida were measured under various conditions of growth. The formation of four of the six enzymes was induced by growth on d- or l-valine: d-amino acid dehydrogenase, branched-chain keto acid dehydrogenase, 3-hydroxyisobutyrate dehydrogenase, and methylmalonate semialdehyde dehydrogenase. Branched-chain amin...

The Escherichia coli aroE gene encoding shikimate dehydrogenase was sequenced. The deduced amino acid sequence was confirmed by N-terminal amino acid sequencing and amino acid analysis of the overproduced protein. The complete polypeptide chain has 272 amino acid residues and has a calculated Mr of 29,380. E. coli shikimate dehydrogenase is homologous to the shikimate dehydrogenase domain of th...

in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...
