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.
