BioPipelines: Accessible Computational Protein and Ligand Design for Chemical Biologists.

Deep learning methods for protein structure generation, sequence design, and structure and property prediction have created unprecedented opportunities for protein engineering and drug discovery. However, using these tools often requires navigating incompatible software environments, diverse input/output formats, and high-performance computing infrastructure, any of which may hinder adoption by primarily experimental chemical biology laboratories. Here, we present BioPipelines, an open-source Python framework that allows researchers to define multistep computational design workflows in a few lines of code. Additionally, its robust yet modular architecture provides a straightforward way to expand the tool kit with different functionalities, particularly by leveraging coding agents, with little effort. The framework currently integrates over 40 tools encompassing structure generation, sequence design, structure prediction, compound screening, and analysis. The same workflow code can be prototyped interactively in a Jupyter notebook and then submitted for production-scale runs without modification. We demonstrate applications in inverse folding, gene synthesis,
