Application
Alanine dehydrogenase (ald) is an oxidoreductase that is involved in taurin/hypotaurine metabolism and CO2 fixation. It is used in various enzyme assays and in kinetic studies .
Biochem/physiol Actions
Alanine dehydrogenase catalyzes the reversible reductive amination of pyruvate using NADH as an oxidation/reduction cofactor .
Unit Definition
1 U corresponds to the amount of enzyme which converts 1 μmol L-alanine per minute at pH 10.0 and 30°C (NAD as cofactor).

The kinetic mechanism of alanine dehydrogenase from soybean nodule bacteroids was studied by initial velocity experiments with or without product inhibitors, dead-end inhibitors, or alternate substrates. Without inhibitors, double-reciprocal plots of initial velocity experiments showed intersecting lines, indicating a sequential

Degradation of the cyanobacterial light-harvesting antenna, the phycobilisome, is a general acclimation response that is observed under various stress conditions. In this study we identified a novel mutant of Synechococcus elongatus PCC 7942 that exhibits impaired phycobilisome degradation specifically during

L-alanine dehydrogenase from Mycobacterium tuberculosis catalyzes the NADH-dependent reversible conversion of pyruvate and ammonia to L-alanine. Expression of the gene coding for this enzyme is up-regulated in the persistent phase of the organism, and alanine dehydrogenase is therefore a potential

This study describes a method to computationally assess the function of homologous enzymes through small molecule binding interaction energy. Three experimentally determined X-ray structures and four enzyme models from ornithine cyclo-deaminase, alanine dehydrogenase, and mu-crystallin were used in combination with

Escherichia coli W was genetically engineered to produce L: -alanine as the primary fermentation product from sugars by replacing the native D: -lactate dehydrogenase of E. coli SZ194 with alanine dehydrogenase from Geobacillus stearothermophilus. As a result, the heterologous alanine
