We have developed an undergraduate biochemistry lab curriculum based on authentic inquiry. Over 3800 structures in the Protein Data Bank have unknown function. Students use structural bioinformatics tools to compare these structures to known enzymes and predict a function. The in silico modules include protein visualization with PyMOL, structural alignment using Dali and ProMOL, sequence exploration with BLAST and Pfam, and ligand docking with PyRX and Autodock Vina. The goal is to predict possible functions for the target enzymes and to identify promising substrates for their active sites. Students then use standard wet-lab biochemistry techniques to express and purify the target enzymes and perform kinetic assays with substrates selected from their docking studies. We are assessing their learning as students and their growth as scientists in terms of research methods, visualization, biological context, and mechanisms of protein function. We have successfully used this curriculum in biochemistry lab courses for majors and non-majors, and we have adapted the experimental modules for implementation in a single course in a single term or across multiple courses. We recently created a GitHub repository for all course materials, and we welcome new collaborators who wish to adopt the curriculum on their own campuses. This project is supported in part by NSF IUSE 1709355.
