Fig. 3: Structure of SO42--bound form of SyHRv.
From: Structural insights into light-driven anion pumping in cyanobacteria
A Overall view of the SyHRv protomer in the membrane. Calculated hydrophobic-hydrophilic membrane boundaries are shown as blue lines. Sulfate ion is shown with spheres. The right section represents the view of the SyHRv trimer from the cytoplasmic side. B Structure of the RSB region. C Coordination of sulfate ions between two protomers. 2Fo-Fc composite omit map is countered around the sulfate ion at 1sigma level. The cofactor retinal and K205 are colored cyan.
