==Overview==

==Crystal structure of Coral pigment==
-
Reef-building corals contain host pigments, termed pocilloporins, that, function to regulate the light environment of their resident microalgae by, acting as a photoprotectant in excessive sunlight. We have determined the, crystal structure of an intensely blue, nonfluorescent pocilloporin to 2.2, A resolution and a genetically engineered fluorescent variant to 2.4 A, resolution. The pocilloporin chromophore structure adopts a markedly, different conformation in comparison with the DsRed chromophore, despite, the chromophore sequences (Gln-Tyr-Gly) being identical; the tyrosine ring, of the pocilloporin chromophore is noncoplanar and in the trans, configuration. Furthermore, the fluorescent variant adopted a noncoplanar, chromophore conformation. The data presented here demonstrates that the, conformation of the chromophore is highly dependent on its immediate, environment.

Reef-building corals contain host pigments, termed pocilloporins, that function to regulate the light environment of their resident microalgae by acting as a photoprotectant in excessive sunlight.

The pocilloporin chromophore structure adopts a markedly different conformation in comparison with the DsRed chromophore, despite the chromophore sequences (Gln-Tyr-Gly) being identical; the tyrosine ring of the pocilloporin chromophore is noncoplanar and in the trans configuration. Furthermore, the fluorescent variant adopted a noncoplanar chromophore conformation.
