These methods built generative models to reveal the underlying constraints of the evolutionary process, which can then be used to infer which mutations are more tolerable or favorable than others. Several ML algorithms have been developed to predict the mutational effects by leveraging the evolutionary information of homologous sequences 14, 15. For example, in one round of directed evolution, the ML model needs to predict the fitness of a sequence that differs from the parent sequence by only one or very few single amino acids. Unlike the qualitative predictions that group protein sequences into different functional classes 10, 11, 12, 13, in protein engineering, a model is required to distinguish quantitative functional levels of closely related sequences.

It takes full advantage of all available sequence and screening data, including those of unimproved variants, thereby traversing the fitness landscape more efficiently.ДЄ critical component of ML-guided directed evolution is to build a machine learning algorithm that accurately maps sequence to function. In contrast to the classical directed evolution, ML-assisted directed evolution can escape from the local optimum by learning the entire functional landscape from data. In one round of directed evolution, the model simulates and predicts the fitness of all possible sequences, and a restricted list of best-performing variants is used as the starting point for the next round of directed evolution. In ML-assisted directed evolution, a machine learning model is trained to learn the sequence-function relationship from sequence and screening data. To address these limitations, machine learning (ML) algorithms have been developed to assist directed evolution, which led to many successfully engineered proteins 4, 5, 6, 7, 8, 9. While directed evolution is highly successful, the protein sequence space that can be sampled by directed evolution is limited and developing an effective high-throughput screening or selection can require a significant experimental effort 4. One powerful protein engineering strategy is directed evolution, which consists of iterative cycles of mutagenesis and high-throughput screening or selection 1, 2, 3. Protein engineering aims to create protein variants with improved or novel functions. Moreover, we used ECNet to guide the engineering of TEM-1 ОІ-lactamase and identified variants with improved ampicillin resistance with high success rates. We show that ECNet predicts the sequence-function relationship more accurately as compared to existing machine learning algorithms by using ~50 deep mutational scanning and random mutagenesis datasets. As such, it enables accurate mapping from sequence to function and provides generalization from low-order mutants to higher-order mutants. This algorithm integrates local evolutionary context from homologous sequences that explicitly model residue-residue epistasis for the protein of interest with the global evolutionary context that encodes rich semantic and structural features from the enormous protein sequence universe. Here, we report ECNet (evolutionary context-integrated neural network), a deep-learning algorithm that exploits evolutionary contexts to predict functional fitness for protein engineering. However, because the general sequence contexts they capture are not specific to the protein being engineered, the accuracy of existing machine learning algorithms is rather limited. Machine learning has been increasingly used for protein engineering. Car brand Model Fuel ECU brand ECU model HW SW.
