Optimizing enzyme thermostability is essential for advancements in protein science and industrial applications. Currently, (semi-)rational design random mutagenesis methods can accurately identify single-point mutations that enhance thermostability. However, complex epistatic interactions often arise when multiple mutation sites are combined, leading to the complete inactivation of combinatorial mutants. As a result, constructing an optimized requires repeated rounds incrementally incorporate single sites, which highly time-consuming. In this study, we developed AI-aided strategy engineering efficiently facilitates recombination beneficial mutations. We utilized data from creatinase, including 18 mutants, 22 double-point 21 triple-point 12 quadruple-point Using these as inputs, used temperature-guided language model, Pro-PRIME, learn features After two design, obtained 50 mutants with superior thermostability, achieving success rate 100%. The best mutant, 13M4, contained 13 maintained nearly full catalytic activity compared wild-type. It showed 10.19°C increase melting temperature ~655-fold half-life at 58°C. Additionally, model successfully captured epistasis high-order sign (K351E) synergistic (D17V/I149V). elucidated mechanism long-range detail using dynamics cross-correlation matrix method. Our work provides efficient framework designing studying effects protein-directed evolution.

Abstract Thermostability is a critical goal in protein engineering for applications of biocatalysts and biomedicines. Despite striking advances biomolecular predictive modeling, reliably identifying stabilizing mutations remains challenging. Previously, molecular dynamics (MD) simulations visual inspection have been used as secondary filter to improve the success rate pre-selected by thermostability algorithms. However, this approach suffers from low throughput subjectivity. Here, we introduce BoostMut (Biophysical Overview Optimal Stabilizing Mutations), computational tool that standardizes automates mutation filtering analyzing dynamic structural features MD. formalizes principles guiding manual verification, providing consistent reproducible stability assessment. Rigorous benchmarking across multiple datasets showed integrating BoostMut’s biophysical analysis improves prediction regardless initial predictor. Given modest amount existing mutant data, performance can be further enhanced with lightweight machine learning model. Upon experimentally validating predictions on enzyme limonene-epoxide hydrolase, identified previously overlooked inspection, achieved higher overall rate. We foresee being filtering, an integrated step workflows, labelling data train future predictors.
