Title: Structural snapshots of V/A-ATPase reveal the rotary catalytic mechanism of rotary ATPases.
Authors: J Kishikawa / A Nakanishi / A Nakano / S Saeki / A Furuta / T Kato / K Mistuoka / K Yokoyama /
Abstract: V/A-ATPase is a motor protein that shares a common rotary catalytic mechanism with FF ATP synthase. When powered by ATP hydrolysis, the V domain rotates the central rotor against the AB hexamer, ...V/A-ATPase is a motor protein that shares a common rotary catalytic mechanism with FF ATP synthase. When powered by ATP hydrolysis, the V domain rotates the central rotor against the AB hexamer, composed of three catalytic AB dimers adopting different conformations (AB, AB, and AB). Here, we report the atomic models of 18 catalytic intermediates of the V domain of V/A-ATPase under different reaction conditions, determined by single particle cryo-EM. The models reveal that the rotor does not rotate immediately after binding of ATP to the V. Instead, three events proceed simultaneously with the 120˚ rotation of the shaft: hydrolysis of ATP in AB, zipper movement in AB by the binding ATP, and unzipper movement in AB with release of both ADP and Pi. This indicates the unidirectional rotation of V/A-ATPase by a ratchet-like mechanism owing to ATP hydrolysis in AB, rather than the power stroke model proposed previously for F-ATPase.

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.
