    Coevolving residues distant from the ligand binding site are involved in GAF domain function by Wesam S. Ahmed (10170053)

    Published 2025
    “…Here, we combine computational and experimental approaches to demonstrate that two highly coevolving residues, L267 and F295, distant from the ligand binding site, play a critical role in GAF domain allostery. Statistical Coupling Analysis (SCA) of GAF domain sequences identified these residues, and molecular dynamics (MD) simulations of both apo and holo forms of wild-type and mutant (L267A, F295A) PDE5 GAFa domains revealed significant changes in structural dynamics and cGMP interaction. …”
