Fig. 2: Structural arrangements of the HiPIP:LH1-RC co-complex at different scales.
From: Crystal structure of a photosynthetic LH1-RC in complex with its electron donor HiPIP
a Crystal packing of the LH1-RC (blue) and HiPIP (red). The rectangular box (blue lines) shows a unit cell and each unit cell contains one HiPIP:LH1-RC. b Anomalous difference Fourier maps measured at 0.9 Å for the C-subunit and HiPIP. Red meshes represent the contour levels around Fe atoms at 4.2σ. c Electron density maps at a contour level of 1.4σ for the interface area between HiPIP (right) and Cyt subunit (left). The 4Fe-4S cluster is shown by a blue box. This figure was drawn using Coot software. d Distances (Å) between the 4Fe-4S cluster in HiPIP and the heme-1 in the Cyt subunit.
