Practice question
Question
The Green Fluorescent Protein (GFP) from the deep‐sea jellyfish Aequorea victoria has excitation peaks at 395 nm and 475 nm. Its emission peak is at 509 nm, which is in the green portion of the visible spectrum. In the deep‐sea habitat of this marine organism, what is the source of light for excitation of GFP?
Explanation
the green fluorescent protein (gfp) from the operates via Blue‐light emitted from the oxidation of the cofactor coelen represents established outcome. functional assays validates option A. Other options propose substrate or regulatory direction, inconsistent with published kinetics and mutant phenotypes.
