Metabolite Identification
Common Name4'-phosphopantetheine
Description4'-phosphopantetheine is a metabolite in the pantothenate and coenzyme A biosynthesis pathway. It can be generated from pantatheine (via pantothenate kinase 1) or R-4'-phospho-pantothenoyl-L-cysteine (via phosphopantothenoylcysteine decarboxylase) or dephospho-CoA (via 4'-phosphopantetheine adenylyl-transferase and ectonucleotide pyrophosphatase). The conversion of 4'-phosphopantetheine (4'-PP) to dephospho-CoA, is catalyzed by 4'-phosphopantetheine adenylyl-transferase. It has been identified as an essential cofactor in in the biosynthesis of fatty acids, polyketides, depsipeptides, peptides, and compounds derived from both carboxylic and amino acid precursors. In particular it is a key prosthetic group of acyl carrier protein (ACP) and peptidyl carrier proteins (PCP) and aryl carrier proteins (ArCP) derived from Coenzyme A. Phosphopantetheine fulfils two demands. Firstly, the intermediates remain covalently linked to the synthases (or synthetases) in an energy-rich thiol ester linkage. Secondly, the flexibility and length of phosphopantetheine chain (approximately 2 nm) allows the covalently tethered intermediates to have access to spatially distinct enzyme active sites.
