1.1.1.103	L-threonine + NAD+ = L-2-amino-3-oxobutanoate + NADH + H+	His94 is an active site residue, substrate binding involved residues Gly66, Gly71, Gly77, and Val80	668567	
1.1.1.103	L-threonine + NAD+ = L-2-amino-3-oxobutanoate + NADH + H+	it is suggested that the unstable L-2-amino-3-oxobutanoate spontaneousely decarboxylates to the stable aminoacetone, there is also some evidence that L-threonine is oxidatively decarboxylated by threonine dehydrogenase to produce aminoacetone	285713
