~~'''~~CRYSTAL STRUCTURE OF C-PHYCOCYANIN FROM SPIRULINA PLATENSIS~~'''~~

===CRYSTAL STRUCTURE OF C-PHYCOCYANIN FROM SPIRULINA PLATENSIS===

~~==Overview==~~

<!--

The ~~crystal structure of C-phycocyanin from~~ the ~~cyanobacterium S. platensis has been determined at 2.2 A resolution. The crystals belong~~ to the ~~monoclinic crystal form, which has not been previously reported for phycobiliprotein structures. The structure was solved using the molecular-replacement method with a final R value of 18~~.~~9% (R(free) = 23~~.7%) ~~after model building and refinement. In the crystals used for the study~~, the C-~~phycocyanin hexamers formed by face~~-to-face association of two trimers are arranged in layers rather than in columns. Three different kinds of packing between adjacent hexamers in the layer were compared. The tight packing of two adjacent hexamers formed by four trimers in the asymmetric unit brings beta155 PCB chromophores close together, so it is possible that lateral energy transfer takes place through the beta155-beta155 route.

The line below this paragraph, {{ABSTRACT_PUBMED_11375497}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 11375497 is the PubMed ID number.
