CC -!- FUNCTION: Catalyzes the NAD(+)-dependent oxidation of L-threonine to 2-
CC amino-3-ketobutyrate. {ECO:0000255|HAMAP-Rule:MF_00627}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-threonine + NAD(+) = (2S)-2-amino-3-oxobutanoate + H(+) +
CC NADH; Xref=Rhea:RHEA:13161, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57926, ChEBI:CHEBI:57945, ChEBI:CHEBI:78948;
CC EC=1.1.1.103; Evidence={ECO:0000255|HAMAP-Rule:MF_00627};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00627};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00627};
CC -!- PATHWAY: Amino-acid degradation; L-threonine degradation via oxydo-
CC reductase pathway; glycine from L-threonine: step 1/2.
CC {ECO:0000255|HAMAP-Rule:MF_00627}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00627}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00627}.
CC -!- SIMILARITY: Belongs to the zinc-containing alcohol dehydrogenase
CC family. {ECO:0000255|HAMAP-Rule:MF_00627}.
