Enzyme Information
| 1.1.1.381 |
3-hydroxy acid dehydrogenase.
based on mapping to UniProt Q05016
L-allo-threonine + NADP(+) = aminoacetone + CO(2) + NADPH.
-!- The enzyme, purified from the bacterium Escherichia coli and the yeast Saccharomyces cerevisiae, shows activity with a range of 3- and 4-carbon 3-hydroxy acids. -!- The highest activity is seen with L-allo-threonine and D-threonine. -!- The enzyme from E.coli also shows high activity with L-serine, D-serine, (S)-3-hydroxy-2-methylpropanoate and (R)-3-hydroxy-2- methylpropanoate. -!- The enzyme has no activity with NAD(+) or L-threonine (cf. EC 1.1.1.103).
