| + | Phycocyanin (PC) is the principal pigment protein in the light-harvesting antenna of cyanobacteria. Here the biochemical characterization and the 1.51A crystal structure of PC from cyanobacterium Nostoc sp. WR13 (Nst-PC) is reported. The P63 crystal lattice is composed of the minimal biological entities of Nst-PC, the (alphabeta)3 trimeric rings. The structure has been refined to R factor 11.5% (Rfree 15.4%) using anisotropic atomic B factors. A phylogenetic study shows that the alpha and beta chains of Nst-PC are significantly clustered in a distinct clade with Acaryochloris marina. The structure was examined to look for any significant differences between Nst-PC and PC from non-desert species. Only minor differences were found in the chromophore microenvironments. The tentative energy transfer pathways in Nst-PC were modeled based on simple structural considerations. | ||
