General description

3-Hydroxybutyrate dehydrogenase (3-HBDH) enzyme, obtained from Rhodobacter sphaeroides, is generally used for the quantification of ketone bodies, such as D-3-hydroxybutyrate and acetoacetate.

Application

3-Hydroxybutyrate Dehydrogenase (3-HBDH) oxidizes selectively (R)-3-hydroxymonocarboxylic acids, or reverse reaction.

Biochem/physiol Actions

3-Hydroxybutyrate dehydrogenase (3-HBDH), a mitochondrial enzyme, catalyzes the reversible oxidation of 3-hydroxybutyrate (3HB) to acetoacetate, with NAD as coenzyme. In mammals, acetyl-coA is metabolized, in one of two pathways, to produce acetoacetate and D-3-hydroxybutyrate, which along with acetone are known as ketone bodies. 3-HBDH reversibly reduces this free acetoacetate to D-3-­hydroxybutyrate. In patients with diabetic ketoacidosis (DKA), the ratio of 3HB and acetoacetate can be as high as 10:1, as compared to the normal ratio of 1:1. 3-HBDH enzyme can be used to detect the quantity of 3HB in urine, serum, and blood samples.

A recombinant form of D-3-hydroxybutyrate dehydrogenase (EC 1.1.1.30) from Pseudomonas fragi has been crystallized by the hanging-drop method using PEG 3000 as a precipitating agent. The crystals belong to the orthorhombic group P2(1)2(1)2, with unit-cell parameters a = 64.3, b

The enzymic determination of D-3-hydroxybutyrate and acetoacetate normally involves the use of 3-hydroxybutyrate dehydrogenase (HBDH, EC 1.1.1.30) of bacterial origin. We show that HBDH from Rhodopseudomonas spheroides (BCL, grade II) contains a 3-hydroxyisobutyrate dehydrogenase (HIBDH) activity: activity with 3-hydroxyisobutyrate as

Precise detection of 3-hydroxybutyrate (HB) in biological samples is of great importance for management of diabetic patients. In this study, an HB biosensor based on single-walled carbon nanotubes (SWCNTs)-modified screen-printed electrode (SPE) was developed to determine the concentration of HB
