The structure of the phycobiliprotein phycoerythrocyanin from the thermophilic cyanobacterium Mastigocladus laminosus has been determined at 2.7 A resolution by X-ray diffraction methods on the basis of the molecular model of C-phycocyanin from the same organism. Hexagonal phycoerythrocyanin crystals of space group P6(3) with cell constants a = b = 156.86(More)
The role of electrostatic interactions between the charges carried by the titratable groups in the different aggregates of constitutive phycocyanin from Fremyella diplosiphon has been studied by using a simple theoretical approach based on the modified Tanford-Kirkwood model. The electrostatic potential has also been calculated by means of a numerical(More)
Constitutive phycocyanin from cyanobacterium Fremyella diplosiphon (Calothrix sp. PCC 7601) grown in green light, has been isolated and crystallized. The crystals belong to the space group R3 with cell constants a = b = 180.26 A, c = 61.24 A, alpha = beta = 90 degrees, gamma = 120 degrees. The crystal structure has been determined by Patterson search(More)
