CC -!- FUNCTION: Catalyzes the reversible reductive amination of pyruvate to
CC L-alanine. However, since the physiological environment of
CC M.tuberculosis has a neutral pH, it can be assumed that the enzyme
CC catalyzes exclusively the formation of L-alanine. May play a role in
CC cell wall synthesis as L-alanine is an important constituent of the
CC peptidoglycan layer (By similarity). {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:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57945, ChEBI:CHEBI:57972; EC=1.4.1.1;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P9WQB1};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250|UniProtKB:P9WQB1};
CC -!- PATHWAY: Amino-acid degradation; L-alanine degradation via
CC dehydrogenase pathway; NH(3) and pyruvate from L-alanine: step 1/1.
CC -!- SUBUNIT: Homohexamer. Trimer of dimers (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the AlaDH/PNT family. {ECO:0000305}.
