Phosphopantothenoylcysteine decarboxylase 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 the third step of the coenzyme A (CoA) biosynthetic pathway, namely the decarboxylation of 4'-phosphopantothenoylcysteine to form 4′-phosphopantetheine. May potentially be part of a larger Coenzyme A-synthesizing protein complex (CPX-396) 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 (this complex). 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.
