Mechanical Features of Plasmodium falciparum Acyl Carrier Protein in the Delivery of Substrates

The Acyl Carrier Protein (ACP) is a key element in the biosynthesis of fatty acids being responsible for the acyl group shuttling and delivery within a series of related enzymes. The molecular mechanism of the delivery process is poorly known, and its characterization is essential for in-depth understanding the biosynthetic machinery. A steered molecular dynamics approach has been applied to shed light on the putative delivery pathway, suggesting the small R3-helix act as gatekeeper for the transfer process. Preventing the delivery mechanism would be an innovative strategy for the development of pathway-based antimalarial compounds
