一般描述

异戊酰辅酶 A 是亮氨酸分解代谢的中间产物。Iv-CoA由β甲基丁酸在酯酰辅酶A合成酶的催化下而合成。在亮氨酸分解代谢途径中,异戊酰辅酶A脱氢酶将异戊酰辅酶A转化为甲基巴豆酰辅酶A。异戊酰辅酶A氧化酶同样也催化脂肪酸β-氧化途径中的这一转化。

应用

异戊酰辅酶A (IV-CoA) 锂盐水合物可用于:
  • 作为G. reessii无细胞抽提物中β-羟基-β-甲基丁酸的合成底物
  • 在高效液相色谱 (HPLC) 中用于表征淋巴细胞中的IV-CoA
  • 在异戊酰辅酶A脱氢酶分析中作为底物

Isovaleryl-coenzyme A (IV-CoA) is the starting unit for some secondary metabolites and iso-odd fatty acids in several bacteria. According to textbook biochemistry, IV-CoA is derived from leucine degradation, but recently an alternative pathway that branches from the well-known mevalonate-dependent isoprenoid

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

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

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)
