Thus, the two substrates of this enzyme are (R)-3-hydroxybutanoate and NAD+, whereas its three products are acetoacetate, NADH, and H+. This enzyme belongs to the family of oxidoreductases, to be specific, those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
This enzyme participates in the synthesis and degradation of ketone bodies and the metabolism of butyric acid.
Synonyms
The systematic name of this enzyme class is (R)-3-hydroxybutanoate:NAD+ oxidoreductase. Other names in common use include:
- NAD+-β-hydroxybutyrate dehydrogenase
- hydroxybutyrate oxidoreductase
- β-hydroxybutyrate dehydrogenase
- D-β-hydroxybutyrate dehydrogenase
- D-3-hydroxybutyrate dehydrogenase
- D-(–)-3-hydroxybutyrate dehydrogenase
- β-hydroxybutyric acid dehydrogenase
- 3-D-hydroxybutyrate dehydrogenase
- β-hydroxybutyric dehydrogenase
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1WMB and 1X1T.
gollark: This is also annoying to program. PRs welcome, of course.
gollark: The disk space is fine, it would just be annoying to program.
gollark: It would be nice to *not* do that in some ways, but not doing that would be... hard.
gollark: So it would have to create an entirely new version of the page on every box toggling, and also map your click to the original position in the source.
gollark: Instead of an event log or something.
