Replacing residues 147 and 204 of this protein with cysteine makes it an effective sensor of a compartment's glutathione redox potential.
Replacing residues 147 and 204 of this protein with cysteine makes it an effective sensor of a compartment's glutathione redox potential. This molecule contains a posttranslationally-formed bond between glycine-67 and serine-65 to form a five-membered ring with tyrosine-66. That structure is located inside this molecule's beta-barrel, which protects the central feature from water. It is commonly used as a reporter gene by fusing it to the gene of interest, which allows one to localize the fusion protein. Osamu Shimomura isolated it from Aequorea victoria, a jellyfish. For 10 points, name this protein often used in biological research that emits a certain color light when excited.
