General description

Coenzyme A (CoA) is a ubiquitous cofactor present in all living organisms. It is synthesized by the enzymatic conjugation of cysteine, pantothenate (Vitamin B5), and adenosine triphosphate (ATP).

Application

Coenzyme A oxidized lithium salt has been used in the preparation of the coenzyme A persulfide (CoASSH) standard to quantify the CoASSH in Staphylococcus aureus strains by tandem mass spectrometry.

Biochem/physiol Actions

Coenzyme A (CoA) plays a role as an acyl-group carrier and carbonyl activator in several biochemical reactions like the tricarboxylic acid cycle and fatty acid metabolism. It acts as a co-factor for several enzymes and is involved in several reactions in intermediary metabolism. CoA contains a thiol group that enables it to take part in several biochemical reactions. Oxidized CoA may be used to study reduction systems (CoA disulfide reductase (CoADR) systems) that regenerate reduced CoA in vivo. Furthermore, oxidized CoA may be used to study the unique functions of this molecule in vivo.

The cdr gene encoding coenzyme A disulfide reductase (CoADR) from Staphylococcus aureus 8325-4 was cloned, sequenced, and overexpressed. The gene encodes a 438-amino acid polypeptide that has a calculated molecular weight of 49,200 and sequence similarity to the pyridine nucleotide-disulfide

Coenzyme A (CoASH) replaces glutathione as the major low molecular weight thiol in Staphylococcus aureus; it is maintained in the reduced state by coenzyme A-disulfide reductase (CoADR), a homodimeric enzyme similar to NADH peroxidase but containing a novel Cys43-SSCoA redox
