The far-red fluorescent protein mKate (lambda(ex), 588 nm; lambda(em), 635 nm; chromophore-forming triad Met(63)-Tyr(64)-Gly(65)), originating from wild-type red fluorescent progenitor eqFP578 (sea anemone Entacmaea quadricolor), is monomeric and characterized by the pronounced pH dependence of fluorescence, relatively high brightness, and high(More)
Here we present the study of the chromophore structure of the purple chromoprotein from Condylactis gigantea. Tandem mass spectrometry and 1H and 13C NMR of the chromopeptide reveal that the protein contains a chromophore with a chemical structure identical to that of the red fluorescent protein from Discosoma sp. A single A63G substitution demonstrates(More)
The three-dimensional structures of the wild-type red (zRFP574) and green (zGFP506) fluorescent proteins (FP) from the button polyp Zoanthus have been determined at 1.51 and 2.2 A resolution, respectively. In addition, the crystal structures of a zGFP506 variant (zGFP506_N66D) with replacement of the first chromophore-forming residue (Asn66 to Asp) have(More)
The three-dimensional structure of the red fluorescent protein (RFP) zRFP574 from the button polyp Zoanthus sp. (two dimers per asymmetric unit, 231 x 4 amino acids) has been determined at 2.4 A resolution in space group C222(1). The crystal structure, refined to a crystallographic R factor of 0.203 (R(free) = 0.249), adopts the beta-barrel fold composed of(More)
