LOW TEMPERATURE STRUCTURE OF PHYCOERYTHROCYANIN FROM MASTIGOCLADUS LAMINOSUS
Overview
Phycoerythrocyanin is the only cyanobacterial phycobiliprotein containing, phycoviolobilin as a chromophore. The phycoviolobilin chromophore is, photo-reactive; upon irradiation, the chromophore undergoes a, Z/E-isomerization involving the rotation of pyrrole-ring D. We have, determined the structure of trimeric phycoerythrocyanin at three different, experimental settings: monochromatically at 110 K and 295 K as well as, with the Laue method at 288 K. Based on their chemical structures, the, restraints for the phycoviolobilin of the alpha-subunit and for the, phycocyanobilin chromophores of the beta-subunit were newly generated, which allows a chemically meaningful refinement of both chromophores. All, three phycoerythrocyanin structures are very similar; the subunits match, within 0.5 A. ... [(full description)]
