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 .
Other Notes
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

The tuberculosis (TB) vaccine strain Mycobacterium bovis BCG is unable to utilise alanine and this deficiency is thought to inhibit the growth of the vaccine in vivo and limit vaccine efficacy. In this report we demonstrate that L-alanine catabolism can

Deletion of both alanine dehydrogenase genes (aldA) in Mesorhizobium loti resulted in the loss of AldA enzyme activity from cultured bacteria and bacteroids but had no effect on the symbiotic performance of Lotus corniculatus plants. Thus, neither indeterminate pea nodules

A degradative pathway for taurine (2-aminoethanesulfonate) in Rhodobacter sphaeroides 2.4.1 was proposed by Brüggemann et al. (2004) (Microbiology 150, 805-816) on the basis of a partial genome sequence. In the present study, R. sphaeroides 2.4.1 was found to grow exponentially

In the diazotrophic filaments of heterocyst-forming cyanobacteria, an exchange of metabolites takes place between vegetative cells and heterocysts that results in a net transfer of reduced carbon to the heterocysts and of fixed nitrogen to the vegetative cells. Open reading
