IUBMB Comments

This enzyme acts in concert with EC 2.3.1.29, glycine C-acetyltransferase, 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.

The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota

Synonyms
threonine dehydrogenase, l-threonine dehydrogenase, l-threonine 3-dehydrogenase, l-thrdh, thrdh, orf382, threonine 3-dehydrogenase, thr dehydrogenase, more
