Abstract

We describe competitive activity-based protein profiling (ABPP) to accelerate the functional prediction and assessment of adenylation (A) domains in nonribosomal peptide synthetases (NRPSs) in proteomic environments. Using a library of sulfamoyloxy-linked aminoacyl-AMP analogs, the competitive ABPP technique offers a simple and rapid assay system for adenylating enzymes and provides insight into Enzyme substrate candidates and Enzyme active-site architecture.
