Abstract excerpt
Library-on-library (LOL) selection screens combinatorial libraries to generate new protein pairs. Previously, LOL selection has only been applied to stable protein-protein interactions. To extend LOL to transient enzyme-substrate pairs, a generalizable sequential LOL trans- and cis-labeling platform is developed, and a proof-of-concept selection is performed on Escherichia coli biotin ligase (BirA) and its...
