제목 Development of Mercury Sensor Using FMN-Based Fluorescent Proteins
초록 Bacterial light-oxygen-voltage-sensing photoreceptor-derived flavin mononucleotide (FMN)- based fluorescent proteins act as a promising distinct class of fluorescent proteins utilized for various biomedical and biotechnological applications. we demonstrated the mercury-sensing ability of FbFP protein and the possible amino acids responsible for metal binding. A ratiometric approach was employed here in order to exploit the fluorescence changes observed at two different emission maxima with respect to Hg at micromolar concentration. The engineered variant FbFPC56I showed high sensitivity towards Hg and followed a good linear relationship from 0.1 to 3 µM of Hg. Thus, further engineering with a rational approach would enable the FbFP to be developed as a novel and highly selective and sensitive biosensor for other toxic heavy metal ions as well.
