Application

3-Hydroxyisobutyrate (HIBA) may be used to study the distribution, characterization and kinetics of enzymes involved in branched chain amino acid metabolism such as 3-hydroxyisobutyrate dehydrogenase (EC: 1.1.1.31) and 3-hydroxyisobutyryl-CoA hydrolase (EC: 3.1.2.4). (R)-β-hydroxyisobutyrate may be used in stereospecific studies.

Biochem/physiol Actions

Increased urinary concentrations of 3-hydroxyisobutyric acid are a biochemical hallmark of metabolic disease 3-hydroxyisobutyric aciduria.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

The branched-chain amino acids (BCAAs)--isoleucine, leucine, and valine--belong to the limited group of substances transported through the blood-brain barrier. One of the functions they are thought to have in brain is to serve as substrates for meeting parenchymal energy demands.

3-hydroxyisobutyric aciduria is an organic aciduria with a poorly understood biochemical basis. It has previously been assumed that deficiency of 3-hydroxyisobutyrate dehydrogenase (HIBADH) in the valine catabolic pathway is the underlying enzyme defect, but more recent evidence makes it likely

The MmsB gene product from Bacillus cereus ATCC14579 exhibits 3-hydroxypropionate dehydrogenase activity. It encodes the 32-kDa enzyme protein composed of 292 amino acids. Recombinant 3-hydroxyisobutyrate dehydrogenase (3-HIBADH) was purified 100-fold from cell extract by ammonium sulfate fractionation and column chromatography.

Valine is one of the three branched-chain amino acids which undergoes oxidation within mitochondria. In this paper, we describe the current state of knowledge with respect to the enzymology of the valine oxidation pathway and the different disorders affecting oxidation.
