Schematic representation of intein-mediated biosensors. Segments either colored brown or enclosed in a brown box indicate an inactive intein or reporter. A. Overview of use of an intein as a biosensor. B. Use of an intein-based system to sense protein-protein interactions. C. Intein-mediated allosteric biosensor for small molecule. D. Intein-mediated biosensor for protease activity. E. Intein-mediated redox biosensor. CFP and YFP are cyan and yellow fluorescent proteins, respectively.
