Entrez Gene Summary for PPCS Gene

  • Biosynthesis of coenzyme A (CoA) from pantothenic acid (vitamin B5) is an essential universal pathway in prokaryotes and eukaryotes. PPCS (EC, one of the last enzymes in this pathway, converts phosphopantothenate to phosphopantothenoylcysteine (Daugherty et al., 2002 [PubMed 11923312]).[supplied by OMIM, Mar 2008]

GeneCards Summary for PPCS Gene

PPCS (Phosphopantothenoylcysteine Synthetase) is a Protein Coding gene. Among its related pathways are Disease and Metabolism. GO annotations related to this gene include phosphopantothenate--cysteine ligase activity.

UniProtKB/Swiss-Prot for PPCS Gene

  • Catalyzes the first step in the biosynthesis of coenzyme A from vitamin B5, where cysteine is conjugated to 4-phosphopantothenate to form 4-phosphopantothenoylcysteine.
