Conditioned free-energy density of proteins using unbalanced solutions to constraint satisfaction problems
arXiv:2606.01329v1 Announce Type: new Abstract: We show that computing the log-partition function (free-energy) of conditioned inhomogeneous Curie--Weiss spin Hamiltonians reduces to an unbalanced $2 \to 1$ norm computation, and design a polynomial-time SDP algorithm for this problem with a lower bound proof for the amount of unbalance achieved. Applied to the protein Ubiquitin, the framework starts from a known crystal structure, explores alternative backbone conformations across the free-energy landscape, and identifies flexible regions of the protein while preserving its native secondary st
This research provides a novel computational approach leveraging advanced algorithms to understand protein dynamics, an area of increasing focus in synthetic biology and AI for drug discovery.
A strategic reader should care as new methods for understanding protein free-energy landscapes could accelerate drug discovery, protein engineering, and the development of new biological materials.
The ability to more accurately and efficiently model protein conformations through computational methods offers a paradigm shift in how biological systems are designed and manipulated.
