Title: Cryo-EM and MD infer water-mediated proton transport and autoinhibition mechanisms of V complex.
Authors: Soung-Hun Roh / Mrinal Shekhar / Grigore Pintilie / Christophe Chipot / Stephan Wilkens / Abhishek Singharoy / Wah Chiu /
Abstract: Rotary vacuolar adenosine triphosphatases (V-ATPases) drive transmembrane proton transport through a V proton channel subcomplex. Despite recent high-resolution structures of several rotary ATPases, ...Rotary vacuolar adenosine triphosphatases (V-ATPases) drive transmembrane proton transport through a V proton channel subcomplex. Despite recent high-resolution structures of several rotary ATPases, the dynamic mechanism of proton pumping remains elusive. Here, we determined a 2.7-Å cryo-electron microscopy (cryo-EM) structure of yeast V proton channel in nanodisc that reveals the location of ordered water molecules along the proton path, details of specific protein-lipid interactions, and the architecture of the membrane scaffold protein. Moreover, we uncover a state of V that shows the -ring rotated by ~14°. Molecular dynamics simulations demonstrate that the two rotary states are in thermal equilibrium and depict how the protonation state of essential glutamic acid residues couples water-mediated proton transfer with -ring rotation. Our cryo-EM models and simulations also rationalize a mechanism for inhibition of passive proton transport as observed for free V that is generated as a result of V-ATPase regulation by reversible disassembly in vivo.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
