CC   -!- FUNCTION: May play a role in cell wall synthesis as L-alanine is an
CC       important constituent of the peptidoglycan layer. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-alanine + NAD(+) = H(+) + NADH + NH4(+) + pyruvate;
CC         Xref=Rhea:RHEA:18405, ChEBI:CHEBI:15361, ChEBI:CHEBI:15377,

CC         ChEBI:CHEBI:57945, ChEBI:CHEBI:57972; EC=1.4.1.1;
CC   -!- PATHWAY: Amino-acid degradation; L-alanine degradation via
CC       dehydrogenase pathway; NH(3) and pyruvate from L-alanine: step 1/1.
CC   -!- SIMILARITY: Belongs to the AlaDH/PNT family. {ECO:0000305}.
