Title: Coordinated conformational changes in the V complex during V-ATPase reversible dissociation.

Abstract: Vacuolar-type ATPases (V-ATPases) are rotary enzymes that acidify intracellular compartments in eukaryotic cells. These multi-subunit complexes consist of a cytoplasmic V region that hydrolyzes ATP ...Vacuolar-type ATPases (V-ATPases) are rotary enzymes that acidify intracellular compartments in eukaryotic cells. These multi-subunit complexes consist of a cytoplasmic V region that hydrolyzes ATP and a membrane-embedded V region that transports protons. V-ATPase activity is regulated by reversible dissociation of the two regions, with the isolated V and V complexes becoming autoinhibited on disassembly and subunit C subsequently detaching from V. In yeast, assembly of the V and V regions is mediated by the regulator of the ATPase of vacuoles and endosomes (RAVE) complex through an unknown mechanism. We used cryogenic-electron microscopy of yeast V-ATPase to determine structures of the intact enzyme, the dissociated but complete V complex and the V complex lacking subunit C. On separation, V undergoes a dramatic conformational rearrangement, with its rotational state becoming incompatible for reassembly with V. Loss of subunit C allows V to match the rotational state of V, suggesting how RAVE could reassemble V and V by recruiting subunit C.

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.
