Computational Scoring and Experimental Evaluation of Enzymes Generated by Neural Networks

Colab notebooks

Notebook	Description
ESM-MSA sampler	uses the ESM-MSA model (a transformer-based neural network trained on protein multiple sequence alignments) to generate new protein sequences by iteratively mutating sequences from an input alignment.
Metrics	Calculates various sequence- and structure-based quality scores for proteins, such as those produced by generative models.
