Structural insight into the role of Gln293Met mutation on the Peloruside A/Laulimalide association with αβ-tubulin from molecular dynamics simulations, binding free energy calculations and weak interactions analysis.

Abstract excerpt

Peloruside A (PLA) and Laulimalide (LAU) are novel microtubule-stabilizing agents with promising properties against different cancer types. These ligands share a non-taxoid binding site at the outer surface of β-tubulin and promote microtubule stabilization by bridging two adjacent αβ-tubulin dimers from parallel protofilaments. Recent site-directed mutagenesis experiments confirmed the existence of a unique...
