Enzyme Information
| 1.1.1.103 |
L-threonine 3-dehydrogenase.
based on mapping to UniProt O58389
L-threonine + NAD(+) = L-2-amino-3-oxobutanoate + NADH.
-!- Acts in concert with EC 2.3.1.29 in the degradation of threonine to glycine. -!- This threonine-degradation pathway is common to prokaryotic and eukaryotic cells and the two enzymes involved form a complex. -!- In aqueous solution, the product L-2-amino-3-oxobutanoate can spontaneously decarboxylate to form aminoacetone.
