  • Maturation of the wild-type fluorophore is quite efficient at 28 degrees, but increasing the temperature to 37 degrees substantially reduces overall maturation and results in decreased fluorescence.

  • Two predominant features of the fluorescent protein fluorophore have important implications for its utility as a probe.

  • It is important to note that the native green fluorescent protein fluorophore exists in two states.

  • For this to work, the researchers must add the gene for the new enzyme, known as a fluorophore ligase, to each cell at the same time that they add the gene for the protein of interest. - latest science and technology news stories 2010

  • The discovery of green fluorescent protein in the early 1960s ultimately heralded a new era in cell biology by enabling investigators to apply molecular cloning methods, fusing the fluorophore moiety to a wide variety of protein and enzyme targets, in order to monitor cellular processes in living systems using optical microscopy and related methodology.

  • It is remarkable that the principle fluorophore is derived from a triplet of adjacent amino acids: the serine, tyrosine, and glycine residues at locations 65, 66, and 67 (referred to as Ser65, Tyr66, and Gly67; see Figure 2).

  • The blue and cyan variants of green fluorescent protein resulted from direct modification of the tyrosine residue at position 66 (Tyr66) in the native fluorophore (see Figure 2).

  • In addition, the fluorophore maturation time is reduced with these modifications.

  • First, the photophysical properties of green fluorescent protein as a fluorophore are quite complex and thus, the molecule can accommodate a considerable amount of modification.

  • The second important feature of green fluorescent protein is that fluorescence is highly dependent on the molecular structure surrounding the tripeptide fluorophore.
