ID   1.1.1.103
DE   L-threonine 3-dehydrogenase.
AN   TDH.
CA   L-threonine + NAD(+) = (2S)-2-amino-3-oxobutanoate + H(+) + NADH.
CC   -!- Acts in concert with EC 2.3.1.29 in the degradation of threonine to
CC       glycine.
CC   -!- This threonine-degradation pathway is common to prokaryotic and
CC       eukaryotic cells and the two enzymes involved form a complex.
CC   -!- In aqueous solution, the product L-2-amino-3-oxobutanoate can
CC       spontaneously decarboxylate to form aminoacetone.
