A Single Arginyl Residue in Plastocyanin and in Cytochrome c6 from the Cyanobacterium Anabaenasp. PCC 7119 Is Required for Efficient Reduction of Photosystem I
(Elsevier, 2001)
Positively charged plastocyanin from Anabaena sp. PCC 7119 was investigated by site-directed mutagenesis. The reactivity of its mutants toward photosystem I was analyzed by laser flash spectroscopy. Replacement of arginine ...

NMR analysis of the transient complex between membrane photosystem I and soluble cytochrome c6
(Elsevier, 2005)
A structural analysis of the surface areas of cytochrome c6, responsible for the transient interaction with photosystem I, was performed by NMR transverse relaxation-optimized spectroscopy. The hemeprotein was titrated by ...

Site-directed Mutagenesis of Cytochromec 6 from Anabaena Species PCC 7119
(Elsevier, 1999)
A number of surface residues of cytochromec 6 from the cyanobacterium Anabaenasp. PCC 7119 have been modified by site-directed mutagenesis. Changes were made in six amino acids, two near the heme group (Val-25 and Lys-29) ...

An evolutionary analysis of the reaction mechanisms of photosystem I reduction by cytochrome c6 and plastocyanin
(Elsevier, 2002)
Photosystem I reduction by the soluble metalloproteins cytochrome c6 and plastocyanin, which are alternatively synthesized by some photosynthetic organisms depending on the relative availability of copper and iron, has ...
