Coenzymes are small organic molecules that supply a varied set of reactive groups to protein enzymes, thereby diversifying catalysis beyond the chemistries of amino acid sidechains. As RNA structures begin with a more limited chemical diversity than proteins, it seems likely that RNA enzymes would also use functional groups from other molecules to ...

Requirement of acetyl-coenzyme A carboxylase kinase for coenzyme A
Archives of Biochemistry and Biophysics, 1983Phosphorylation and inactivation of acetyl-coenzyme A (CoA) carboxylase by acetyl-CoA carboxylase kinase in the presence of ATP and Mg2+ requires coenzyme A. Coenzyme A did not enhance the phosphorylation of alternative substrates of the carboxylase kinase such as protamine or histones.

Synthesis of arachidonoyl coenzyme A and docosahexaenoyl coenzyme A in retina
Current Eye Research, 1984The synthesis of 14C-labeled arachidonoyl coenzyme A (CoA) and docosahexaenoyl CoA was studied in the human, bovine, rat and frog retina. The synthesis of arachidonoyl CoA was two- to fourfold higher than that of docosahexaenoyl CoA in the retinal membranes examined.

Analytica Chimica Acta, 2008 Hepatic acyl-coenzyme A synthetase (ACS), carnitine palmitoyltransferase-I (CPT-I) and acetyl coenzyme A carboxylase (ACC) are coenzymes associated with the genetic type of obesity in animal models. This paper reports the use of microchip electrophoresis

Coenzymes II: Metallic Coenzymes
2007The original coenzymes were small organic molecules that activated enzymes and participated directly in catalyzing enzymatic reactions. Most of them were derived from vitamins and were known as biologically “activated” forms of vitamins such as niacin, riboflavin, thiamine, and pyridoxal.

Fetal Diagnosis and Therapy, 2009
Our objectives were to assess the plasma coenzyme Q10 (CoQ10) levels in normal pregnancy, in pregnancy with a spontaneous contractile event, in spontaneous abortion and in threatened abortion. Six hundred and fifteen CoQ10 levels were analyzed in 483 pregnant women: 350 patients were employed to design a normal curve; 66 patients with spontaneous ...
