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.

Coenzymes I: Organic Coenzymes
2007Most enzymatic reactions proceed with chemical changes that cannot be brought about by the side chains of amino acid residues. These enzymes function in cooperation with coenzymes and cofactors, which lend physicochemical potentialities not found in amino acids.

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.

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 ...
