A general Temperature-Guided Language model to engineer enhanced Stability and Activity in Proteins

Designing protein mutants with high stability and activity is a critical yet challenging task in protein engineering. Here, we introduce PRIME, an innovative deep learning approach for the zero-shot prediction of both protein stability and enzymatic activity. PRIME leverages temperature-guided language modelling, providing robust and precise predictions without relying on prior experimental mutagenesis data. Tested against 33 protein datasets, PRIME demonstrated superior predictive performance and generalizability compared to current state-of-the-art models
