Here, we present cryo-electron microscopy structures of human HCN1 corresponding to Closed, Open, and a putative Intermediate state. Our structures reveal that the downward motion of the gating charges past the charge transfer center is accompanied by concomitant unwinding of the inner end of the...
We employed the QTAIM method to analyze the electronic structure of the complexes. Figure2shows the contour plots of the Laplacian of electron density (∇2ρ(r)) at the Zn–B–N and Zn–Mn–C planes of Zn(NHBMe)2and Zn[Mn(CO)5]2complexes, respectively. The Laplacian distributions of...
