Biochemistry, mutagenesis, and oligomerization of DsRed, a red fluorescent protein from coral.
DsRed is a recently cloned 28-kDa fluorescent protein responsible for the red coloration around the oral disk of a coral of the Discosoma genus. DsRed has attracted tremendous interest as a potential expression tracer and fusion partner that would be complementary to the homologous green fluorescent protein from Aequorea, but very little is known of the biochemistry of DsRed. We now show that D...
متن کاملRefined crystal structure of DsRed, a red fluorescent protein from coral, at 2.0-A resolution.
The crystal structure of DsRed, a red fluorescent protein from a corallimorpharian, has been determined at 2.0-A resolution by multiple-wavelength anomalous dispersion and crystallographic refinement. Crystals of the selenomethionine-substituted protein have space group P2(1) and contain a tetramer with 222 noncrystallographic symmetry in the asymmetric unit. The refined model has satisfactory ...
متن کاملThe structure of the chromophore within DsRed, a red fluorescent protein from coral.
DsRed, a brilliantly red fluorescent protein, was recently cloned from Discosoma coral by homology to the green fluorescent protein (GFP) from the jellyfish Aequorea. A core question in the biochemistry of DsRed is the mechanism by which the GFP-like 475-nm excitation and 500-nm emission maxima of immature DsRed are red-shifted to the 558-nm excitation and 583-nm emission maxima of mature DsRed...
متن کاملRed fluorescent protein DsRed from Discosoma sp. as a reporter protein in higher plants.
GFP from Aequorea victoria is a standard genetic marker widely used to visualize cellular events in a noninvasive manner. For simultaneous imaging of different processes, in vivo mutants of GFP with shifted wavelength spectra (e.g., blue fluorescent protein) are conventionally used. The recently reported red fluorescent protein from Discosoma sp., DsRed, represents a new marker that can be used...
متن کاملMolecular spectroscopy and dynamics of intrinsically fluorescent proteins: coral red (dsRed) and yellow (Citrine).
Gene expression of intrinsically fluorescent proteins in biological systems offers new noninvasive windows into cellular function, but optimization of these probes relies on understanding their molecular spectroscopy, dynamics, and structure. Here, the photophysics of red fluorescent protein (dsRed) from discosoma (coral), providing desired longer emission/absorption wavelengths, and an improve...
