#SIMPLAIX26

March is here; spring is near... how many creatures can you hear? From the tiniest insect to the largest bird, they all contribute to the soundscape of the HITS garden. Ready for a new part of life, the toads in our ponds also croak a love song of sorts. Curious? Listen to their serenade here. 🐸

Coarse-Grained Martini 3 Model of Chondroitin Sulfate A Chondroitin sulfate A (CSA) is a negatively charged linear glycosaminoglycan that plays a vital role in many biological processes. Research on CSA has been challenging due to its size, chemical heterogeneity, and multitude of binding partners. To address these issues, we developed a model of CSA for coarse-grained molecular dynamics simulations based on the Martini 3 force field. We demonstrate that this model is capable of reproducing atomistic properties of the repeating CSA disaccharide unit, including its molecular volume, bonded interactions, and structural polymer properties of CSA chains of different lengths. In particular, for biologically relevant long chains and despite using an explicit solvent, the computational cost is significantly reduced, relative to the cost equivalent atomistic simulations would require. The compatibility of the model with the Martini Go̅ protein model was tested by retrieving the force–response relationship of the CSA–malaria adhesin VAR2CSA complex. Importantly, we explored the influence of electrostatics on CSA aggregation. We show that the default Martini 3 parameters lead to overaggregation. We provide at least three different strategies to alleviate this issue, making use of a bigger bead for sodium cations, reflecting their hydration shell, partial ionic charges as a mean-field resource to take into account electronic polarizability, and, optionally, particle mesh Ewald summation as a more robust treatment of long-range electrostatics. Our model enables predictive modeling of CSA and potentially other chondroitin sulfates with the Martini 3 force field. In addition, this model provides insights for the further development of coarse-grained models of highly charged systems.

🧪 Simulating large biomolecules without massive compute costs

This new study from the group Frauke Gräter presents a coarse-grained model of chondroitin sulfate A (CSA) using the Martini 3 framework.

Ever wondered how to make economic forecast honest, transparent, and user-friendly?

@kit.edu and HITS researchers show a simple method that:

💡 Quantifes uncertainty
💡 Beats or matches traditional models
💡 Offers real-time interval forecasts
