The green fluorescent protein (GFP)-like fluorescent proteins play an important role for the color of reef-building corals. Different colors of extant coral fluorescent proteins (FPs) have evolved from a green ancestral protein. Interestingly, green-to-red photoconversion FPs (Kaede-type Red FPs) are only found in clade D from Scleractinia (Faviina suborder). Therefore, I focus on the evolution of Kaede-type FPs from Faviina suborder ancestral FP. A total of 13 mutations have been identified previously that recapitulate the evolution of Kaede-type red FPs from the ancestral green FP. To examine the effect of each mutation, total ten reconstructed FPs were analyzed and six …

Acquisition of fluorescence via autocatalytic processes is unique to few proteins in the natural world. Fluorescent proteins (FPs) have been integral to live-cell imaging techniques for decades; however, mechanistic information is still emerging fifty years after the discovery of the original green fluorescent protein (GFP). Modification of the fluorescence properties of the proteins derived from GFP allows increased complexity of experiments and consequently, information content of the data acquired. The importance of arginine-96 in GFP has been widely discussed. It has been established as vital to the kinetics of chromophore maturation and to the overall fold of GFP before post-translational …
