Artificial metalloenzyme biosensor of ethylene gas in fruits andplants

摘要

Using artificial metalloenzymes (ArM),the unique opportunity exists to designbiosensors for difficult-to-detect metabolites.One such example is ethylene gas,which is awell-characterized phytohormone that plays a major role in regulating many aspects of plantgrowth,immunity,and development.The focus of this work is the design and developmentof an ArM-based biosensor,which can produce turn-on fluorescence in the presence ofethylene via cross metathesis.
