Application
L-Alanine dehydrogenase converts L-alanine to pyruvate and ammonium. L-Alanine dehydrogenase from Bacillus subtilis may be used to study enzyme inactivation and protection .
Biochem/physiol Actions
L-Alanine dehydrogenase is an A-stereospecific dehydrogenase that catalyzes the reversible deamination of L-alanine to pyruvate and ammonium. It is important for the generation of pyruvate during sporulation. L-Alanine dehydrogenase from Bacillus subtilis has a predominately ordered kinetic mechanism in which NAD binds before L-alanine. Subsequently, ammonia, pyruvate, and NADH are released in that specific order. Optimal pH for the amination reaction is 8.8-9.0, whereas it is 10-10.5 for the deamination reaction. The enzyme is inactivated by divalent metal ions and p-chloromercuribenzoate, mercuric ion being most effective. The inactivation may be reversed by L- or D-cysteine.

L-Alanine dehydrogenase from Bacillus subtilis was inactivated with two different lysine-directed chemical reagents, i.e. 2,4, 6-trinitrobenzenesulfonic acid and N-succinimidyl 3-(2-pyridyldithio)propionate. In both cases, the inactivation followed pseudo first-order kinetics, with a 1:1 stoichiometric ratio between the reagent and the enzyme

γ-Aminobutyric acid (GABA) accumulates in many plant species in response to environmental stress. However, the physiological function of GABA or its metabolic pathway (GABA shunt) in plants remains largely unclear. Here, the genes, including glutamate decarboxylases (SlGADs), GABA transaminases (SlGABA-Ts) and

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

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
