NMR solution structure of the reduced spinach plastocyaninNMR solution structure of the reduced spinach plastocyanin
Structural highlights
Function[PLAS_SPIOL] Participates in electron transfer between P700 and the cytochrome b6-f complex in photosystem I. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedIn oxygenic photosynthesis, plastocyanin shuttles electrons between the membrane-bound complexes cytochrome b6f and photosystem I. The homologous complex between cytochrome f and plastocyanin, both from spinach, is the object of this study. The solution structure of the reduced spinach plastocyanin was determined using high field NMR spectroscopy, whereas the model structure of oxidized cytochrome f was obtained by homology modeling calculations and molecular dynamics. The model structure of the intermolecular complex was calculated using the program AUTODOCK, taking into account biological information obtained from mutagenesis experiments. The best electron transfer pathway from the heme group of cytochrome f to the copper ion of plastocyanin was calculated using the program HARLEM, obtaining a coupling decay value of 1.8 x 10(-4). Possible mechanisms of interaction and electron transfer between plastocyanin and cytochrome f were discussed considering the possible formation of a supercomplex that associates one cytochrome b6f, one photosystem I, and one plastocyanin. Structure of the intermolecular complex between plastocyanin and cytochrome f from spinach.,Musiani F, Dikiy A, Semenov AY, Ciurli S J Biol Chem. 2005 May 13;280(19):18833-41. Epub 2005 Feb 3.
