Cyclic GMP-AMP Synthase (cGAS) is activated upon DNA binding and catalyzes the synthesis of 2′,3′-cGAMP from GTP and ATP. This cyclic dinucleotide is a messenger that triggers the autoimmune system of eukaryotic cells. In this study, we propose a Molecular Dynamics (MD) investigation of cGAS activation. We notably provide insights into the motion of the activation loop, both from a mechanical point of view and considering its role in the catalysis of cGAMP production. We finally shed light on the reaction resulting in cGAMP synthesis. Two possible catalytic routes (referred to as GTP-ATP and ATP–GTP) are proposed based on the active site occupancy, paving the way toward further exploration of the reaction mechanism.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
