1H AND 15N SEQUENTIAL ASSIGNMENT, SECONDARY STRUCTURE AND TERTIARY FOLD OF [2FE-2S] FERREDOXIN FROM SYNECHOCYSTIS SP. PCC 6803
Overview
The [2Fe-2S] ferredoxin extracted from Synechocystis sp. PCC 6803 was studied by 1H and 15N nuclear magnetic resonance. Sequence-specific 1H and 15N assignment of amino acid residues far from the paramagnetic cluster (distance higher than 8 A) was performed. Interresidue NOE constraints have allowed the identification of several secondary structure elements: one beta sheet composed of four beta strands, one alpha helix, and two alpha helix turns. The analysis of interresidue NOEs suggests the existence of a disulfide bridge between the cysteine residues 18 and 85. Such a disulfide bridge has never been observed in plant-type ferredoxins. Structure modeling using the X-PLOR program was performed with or without assuming the existence of a disulfide bridge. As a result, two structure families were obtained with rms deviations of 2.2 A. Due to the lack of NOE connectivities resulting from the paramagnetic effect from the [2Fe-2S] cluster, the structures were not well resolved in the region surrounding the [2Fe-2S] cluster, at both extremities of the alpha helix and the C and N terminus segments. In contrast, when taken separately, the beta sheet and the alpha helix were well defined. This work is the first report of a structure model of a plant-type [2Fe-2S] Fd in solution.
