'''Crystal structure of Coral protein mutant'''
===Crystal structure of Coral protein mutant===




==Overview==
<!--
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.
The line below this paragraph, {{ABSTRACT_PUBMED_12623015}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 12623015 is the PubMed ID number.
