Chromophore

These single - and double-cone sensitivities were estimated based on two assumptions: (1) the visual pigment λ max for each gene is the same for all species; and (2) the chromophore is A1 (11 - cis retinal) for all species. ❋ Christopher M. Hofmann Et Al. (2009)

Dr. Roger Tsien of University of California, San Diego, engineered GFP by modifying the amino acid residues surrounding the chromophore, producing many different fluorescent proteins that emit various colors, from blue to red. ❋ Unknown (2009)

Our first paper on Cypridina luciferin was published in 1957, although the chromophore structure of luciferin remained to be elucidated. ❋ Unknown (2009)

At that time, however, it was commonly believed that expressing the cDNA in living organisms would not produce fluorescent GFP, because the formation of its chromophore requires the reactions of condensation and dehydrogenation that are not expected to occur spontaneously. ❋ Unknown (2009)

In 1972, back at Princeton, we succeeded in determining the structure of AF350, a part of the aequorin chromophore. ❋ Unknown (2009)

Before leaving Princeton, I elucidated the chromophore of GFP (Shimomura, 1979). ❋ Unknown (2009)

If the disappearance of the jellyfish had occurred 20 years earlier, we wouldn't have been able to learn the mechanism of the aequorin bioluminescence reaction, as well as the chromophore of GFP. ❋ Unknown (2009)

[RT] And that's a strange paradoxical phenomenon because we discovered that almost any mutation of one amino acid right next to the chromophore will shift it to being all of one or all of the other – either all UV or all blue. ❋ Unknown (2008)

The third act of the GFP story began in 1994, when Roger Tsien explained how the chromophore of GFP can form spontaneously in the presence of oxygen and engineered a GFP variant with blue fluorescence, demonstrating that point mutations in the primary structure of GFP can modulate its fluorescence emission spectrum. ❋ Unknown (2008)

It was generally assumed that formation of its chromophore would require enzymes specific to A. victoria, but there was one GFP believer named Martin Chalfie who had a different view. ❋ Unknown (2008)

They fluoresce throughout the whole visible spectrum, have enhanced photostability and brightness as well as greatly reduced time for their chromophore to mature into its fluorescent state after protein folding. ❋ Unknown (2008)

The similarity of action spectra for thymine dimers in human epidermis and erythema suggests that DNA is the chromophore for erythema. ❋ Unknown (2009)

In this case, the spectral shift is produced by a photo-induced modification involving a break in the peptide backbone adjacent to the chromophore. ❋ Unknown (2005)

The family of yellow fluorescent proteins was initiated after the crystal structure of green fluorescent protein revealed that threonine residue 203 (Thr203) was near the chromophore. ❋ Unknown (2005)

Mutation of this residue to tyrosine was introduced to stabilize the excited state dipole moment of the chromophore and resulted in a 20-nanometer shift to longer wavelengths for both the excitation and emission spectra. ❋ Unknown (2005)

In transient optical experiments the absorbed photon raises the vibrational temperature of the chromophore. ❋ Unknown (2006)

And in tomorrow's world, rewards came to those who successfully fashioned a new lip sparkle, eye filter, or follicular chromophore. ❋ Foster, Alan Dean, 1946- (2003)

When a light quantum is taken up by the visual pigment the chromophore changes its form: there is an isomerization from II-cis to all-trans. ❋ Unknown (1968)

One, containing vitamin A, the smaller piece or the chromophore, fits like a hooked puzzle piece in the surface profile of the larger protein piece, the opsin. ❋ Unknown (1968)

University of Alabama has received funding to study our chromophore for use in photovoltaic cells.
