General description

Isovaleryl coenzyme A is an intermediate in leucine catabolism. Iv-CoA is synthesized from β-methylbutyric acid by the action of enzyme acyl CoA synthetase. The conversion of isovaleryl-CoA to methylcrotonyl-CoA is catalyzed by the enzyme isovaleryl-CoA dehydrogenase in leucine catabolism pathway. The enzyme isovaleryl-CoA oxidase also calalyzes this conversion in fatty acid β-oxidation pathway.

Application

Isovaleryl coenzyme A (IV-CoA ) lithium salt hydrate may be used:
  • as substrate for β-Hydroxy-β-methylbutyric acid synthesis in cell-free extracts from G. reessii
  • in high-performance liquid chromatography (HPLC) for the characterization of IV-CoA from lymphocytes
  • as a substrate in isovaleryl-CoA dehydrogenase assay

Galactomyces reessii accomplishes the enzymatic transformation of beta-methylbutyric acid (isovaleric acid) to beta-hydroxy-beta-methylbutyric acid. The enzymatic basis for this bioconversion was evaluated by analyzing cell-free extracts of G. reessii for enzyme activities commonly associated with leucine catabolism. G. reessii extracts

We recently identified a cDNA encoding a putative isovaleryl-coenzyme A (CoA) dehydrogenase in Arabidopsis (AtIVD). In animals, this homotetrameric enzyme is located in mitochondria and catalyzes the conversion of isovaleryl-CoA to 3-methylcrotonyl-CoA as an intermediate step in the leucine (Leu)

Maple syrup urine disease (MSUD) is caused by a congenital defect of the branched-chain alpha-ketoacid dehydrogenase complex (BCKADC), and is one of the target disorders in newborn screening. However, it is not always easy to confirm the diagnosis; conventional methods

Isovaleryl-CoA (IV-CoA) is usually derived from the degradation of leucine by using the Bkd (branched-chain keto acid dehydrogenase) complex. We have previously identified an alternative pathway for IV-CoA formation in myxobacteria that branches from the well-known mevalonate-dependent isoprenoid biosynthesis pathway.

A biosynthetic shunt pathway branching from the mevalonate pathway and providing starter units for branched-chain fatty acid and secondary metabolite biosynthesis has been identified in strains of the myxobacterium Stigmatella aurantiaca. This pathway is upregulated when the branched-chain alpha-keto acid
