CHEMICAL1 and enzymic2 studies from these two laboratories suggested that coenzyme A is best represented by formula (I) (cf. ref. 3). While the synthesis of various fragments of the molecule4 has lent considerable support to this structure, the enzymic and chemical evidence did not agree on one point.

Biochimica et Biophysica Acta (BBA) - General Subjects, 1961
Abstract An improved procedure for the chemical synthesis of coenzyme A by anhydride-anion exchange is described. A mixture of the 2′,5′- and 3′,5′-diphosphastes of adenosine is treated with diphenylphosphorochloridate to give P 1 -adenosine (2′3′-cyclic phosphate)-5′- P 2 -diphenylpyrophosphate quantitatively. This is then treated with pantethine

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.

Efficient Synthesis of Radiolabeled Propionyl-Coenzyme A and Acetyl-Coenzyme A
Analytical Biochemistry, 1995The efficient microscale synthesis of [1-14C]propionyl-CoA from commercially available sodium [1-14C]-propionate using 1,1'-carbonyldiimidazole in yields of nearly 70% is reported for the first time. A substantial improvement in the process for making [1-14C]acetyl-CoA from sodium [1-14C]acetate was also achieved.

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.

An assay for 3-oxoacyl-coenzyme A (3-oxoacyl-CoA) thiolases is described. The reaction utilizes acetyldithio-CoA as the nucleophile and variable chain length saturated acyl-CoA's as the electrophiles. The properties of the 3-oxoacyl-CoA dithioester product, notably a pKa of 6.6 +/- 0.1 and an extinction coefficient of 21,600 cm-1 M-1 for the ...

PRENATAL DIAGNOSIS OF SUCCINYL‐COENZYME A:3‐KETOACID COENZYME A TRANSFERASE DEFICIENCY
Prenatal Diagnosis, 1996Succinyl-CoA:3-ketoacid CoA transferase (SCOT) deficiency is a rare disorder of ketone body catabolism. In the present study, we prenatally diagnosed SCOT deficiency in a fetus in a family of which the proband was the first patient with SCOT deficiency identified in Japan, by analysis of enzyme activity levels in samples of chorionic villi and cultured

Publisher Summary When a coenzyme is immobilized for affinity chromatography, the immobilized coenzyme may be used for the purification of enzymes requiring it for activity. Conversely, when an enzyme or a group of enzymes requiring a coenzyme is immobilized, the immobilized enzyme or enzymes may be useful for the purification of the coenzyme.
