應用
Acetyl-CoA carboxylase is responsible for synthesis of Malonyl-CoA which is an inhibitor of fatty acid oxidation in skeletal muscle mitochondria. The enzyme may be used to study the effect on production of malonyl-CoA as well as fatty acid oxidation during exercise. The enzyme also may be used for ACC regulation study in anti-obesity and anti-type 2 diabetes therapeutics.
生化／生理作用
Acetyl-CoA Carboxylase (ACC) regulates the metabolism of fatty acids. This enzyme catalzes the formation of Malonyl CoA through the irreversible carboxylation of acetyl CoA. There are two main isoforms of Acetyl-CoA carboxylase expressed in mammals, Acetyl-CoA carboxylase 1 (ACACA) and Acetyl-CoA carboxylase 2 (ACACB). ACACA has broad tissue distribution but is enriched in tissues critical for fatty acid sythesis such as adipose tissue. ACACB is enriched in tissues such as skeletal muscle and heart that are critical for fatty acid oxidation.
The Acetyl-CoA Carboxylase enzymes are activated by citrate, glutamate, and dicarboxylic acids and negatively regulated by long and short chain fatty acyl CoAs. Because of thier roles in fatty acid metabolism and oxidation, ACACA and ACACB are therapeutic targets for treating obesity and metabolic syndrome disorders.

Malonyl-CoA, an inhibitor of fatty acid oxidation in skeletal muscle mitochondria, decreases in rat skeletal muscle during exercise or in response to electrical stimulation. Regulation of rat skeletal muscle acetyl-CoA carboxylase (ACC), the enzyme that synthesizes malonyl-CoA, was studied in

The metabolic role of 5'AMP-activated protein kinase (AMPK) in regulation of skeletal muscle metabolism in humans is unresolved. We measured isoform-specific AMPK activity and beta-acetyl-CoA carboxylase (ACCbeta) Ser(221) phosphorylation and substrate balance in skeletal muscle of eight athletes at rest

Malonyl-CoA, generated by acetyl-CoA carboxylases ACC1 and ACC2, is a key metabolite in the control of fatty acid synthesis and oxidation in response to dietary changes. ACC2 is associated to the mitochondria, and Acc2-/- mice have a normal lifespan and

Degradation of unusual fatty acids through β-oxidation within transgenic plants has long been hypothesized as a major factor limiting the production of industrially useful unusual fatty acids in seed oils. Arabidopsis seeds expressing the castor fatty acid hydroxylase accumulate hydroxylated

While allosteric activation of AMPK is triggered only by AMP, binding of both ADP and AMP has been reported to promote phosphorylation and inhibit dephosphorylation at Thr172. Because cellular concentrations of ADP and ATP are higher than AMP, it has
