PPAT catalyzes the reversible transfer of an adenylyl group from Mg2+:ATP to 4′-phosphopantetheine to form 3′-dephospho-CoA (dPCoA) and pyrophosphate.
WebOct 5, 2007 · Together with docking simulations that identified a potential phosphopantetheine binding groove, the structural and functional studies reveal that the C9 specificity is a result of active site geometry and substrate ring constraints. The results lay the foundation for the design of novel aromatic polyketide natural products with different ... WebJan 3, 2024 · Lipoic acid is a sulfur containing cofactor, indispensable for the function of several metabolic enzymes. In microorganisms, lipoic acid can be salvaged from the surroundings by Lipoate protein ligase A (LplA), an ATP-dependent enzyme. Alternatively, it can be synthesized by the sequential action of Lipoate protein ligase B (LipB) and Lipoyl …

Node Color colored nodes: WebPantetheine Phosphate. Phosphopantetheine tethering is a posttranslational modification that takes place on the active site serine of carrier proteins138 – ‘acyl carrier proteins (ACPs) and peptidyl carrier proteins (PCPs), also termed thiolation (T) domains’ – during the biosynthesis of fatty acids (FAs) (use ACPs) (Scheme 23), polyketides (PKs) (use ACPs) …
WebUsing Escherichia coli LipB as a model enzyme, we show here that the octanoyl-transferase mainly recognizes the 4'-phosphopantetheine-tethered acyl-chain of its donor substrate and weakly binds the apo-acyl carrier protein. We demonstrate LipB can accept octanoate from its own ACP and noncognate ACPs, as well as C8-CoA.
