WebThe CP tethers the growing intermediates on a 4′-phosphopantetheine (PPant) arm of 20 Å through a reactive thioester linkage. PPant is thought of as a “prosthetic arm” on which all substrates and intermediates of these pathways are covalently yet transiently held during the orderly progression of enzymatic modifications to the extending ... WebOct 3, 2003 · 1. ). In coenzyme A, 4′-phosphopantetheine is covalently linked to an adenylyl group, whereas it is covalently linked to a serine hydroxyl group in acyl carrier proteins. 4′-phosphopantetheine is cofactor of enzymes that play a role in the biosynthesis of fatty acids, polypeptide antibiotics, and polyketides (. 2. ).
