General annotation (Comments)

Function	This enzyme is a key factor in the assimilation of L-alanine as an energy source through the tricarboxylic acid cycle during sporulation.
Catalytic activity	L-alanine + H2O + NAD+ = pyruvate + NH3 + NADH.
Pathway	Amino-acid degradation; L-alanine degradation via dehydrogenase pathway; NH(3) and pyruvate from L-alanine: step 1/1.
Subunit structure	Homohexamer.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the AlaDH/PNT family.
biophysicochemical properties	Temperature dependence: Loses about 50% of its initial activity when heated at 65 degrees Celsius for 5 min.
