>TIGR00692 tdh L-threonine 3-dehydrogenase; InterPro: IPR004627 L-threonine 3-dehydrogenase (1.1.1.103 from EC) is a tetrameric, zinc-binding, NAD-dependent enzyme of threonine catabolism. It catalyses the conversion of L-threonine and NAD+ to L-2-amino-3-oxobutanoate and NADH. In Escherichia coli His-90 modulates substrate specificity and is believed part of the active site. Closely related proteins include sorbitol dehydrogenase, xylitol dehydrogenase, and benzyl alcohol dehydrogenase. Eukaryotic examples of this enzyme have been demonstrated experimentally but are not detected by this HMM. ; GO: 0008270 zinc ion binding, 0008743 L-threonine 3-dehydrogenase activity, 0006567 threonine catabolic process.
