Coenzyme A-synthesizing protein complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Catalyses multiple steps in the coenzyme A (CoA) biosynthetic pathway, with the CAB3 protein potentially acting as a scaffold to which other enzymes bind. This may be a larger complex, also incorporating the Phosphopantothenoylcysteine decarboxylase complex (CPX-393) but this is not yet clear. The synthesis of CoA involves the phosphorylation of pantothenate (vitamin B5) to 4'-phosphopantothenate, to which a cysteine is then added to form 4'-phospho-N-pantothenoylcysteine (PCC). PPC is decarboxylated to 4'-phosphopantetheine by phosphopantothenoylcysteine decarboxylase (CPX-393). 4'-phosphopantetheine is adenylylated to form dephospho-CoA which is then phosphorylated to form coenzyme A.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
