== Publication Abstract from PubMed ==
Phycocyanin is a phycobiliprotein involved in light harvesting and conduction of light to the reaction centers in cyanobacteria and red algae. The structure of C-phycocyanin from Gracilaria chilensis was solved by X-ray crystallography at 2.0 A resolution in space group P2(1). An interaction model between two PC heterohexamers was built, followed by molecular dynamic refinement. The best model showed an inter-hexamer rotation of 23 degrees . The coordinates of a PC heterohexamer (alphabeta)(6) and of the PC-PC complex were used to perform energy transfer calculations between chromophores pairs using the fluorescence resonance energy transfer approach (FRET). Two main intra PC ((I)beta(3)(82)--&gt;(I)alpha(1)(84)--&gt;(I)alpha(5)(84)--&gt;(I)beta(6)(82) and (I)beta(3)(153)--&gt;(I)beta(5)(153)) and two main inter PC ((I)beta(6)(82)--&gt;(II)beta(3)(82) and (I)beta(5)(153)--&gt;(II)beta(3)(153)) pathways were proposed based on the values of the energy transfer constants calculated for all the chromophore pairs in the hexamer and in the complex.
