Utilizing Mechanistic Cross-Linking Technology to Study Protein-Protein Interactions: An Experiment Designed for an Undergraduate Biochemistry Lab.

Over the past decade, mechanistic crosslinking probes have been used to study protein-protein interactions in natural product biosynthetic pathways. This approach is highly interdisciplinary, combining elements of protein biochemistry, organic chemistry, and computational docking. The development of an experiment to engage undergraduate students in multidisciplinary research is described that leverages mechanistic crosslinking probes to study protein conformations and protein-protein interactions. This experiment provides students with a platform to learn chemoenzymatic synthesis, polyacrylamide gel electrophoresis, biochemical assays, and computational docking all while exploring a contemporary biochemical topic.
