Title: Structure of mycobacterial ATP synthase bound to the tuberculosis drug bedaquiline.
Authors: Hui Guo / Gautier M Courbon / Stephanie A Bueler / Juntao Mai / Jun Liu / John L Rubinstein /
Abstract: Tuberculosis-the world's leading cause of death by infectious disease-is increasingly resistant to current first-line antibiotics. The bacterium Mycobacterium tuberculosis (which causes tuberculosis) ...Tuberculosis-the world's leading cause of death by infectious disease-is increasingly resistant to current first-line antibiotics. The bacterium Mycobacterium tuberculosis (which causes tuberculosis) can survive low-energy conditions, allowing infections to remain dormant and decreasing their susceptibility to many antibiotics. Bedaquiline was developed in 2005 from a lead compound identified in a phenotypic screen against Mycobacterium smegmatis. This drug can sterilize even latent M. tuberculosis infections and has become a cornerstone of treatment for multidrug-resistant and extensively drug-resistant tuberculosis. Bedaquiline targets the mycobacterial ATP synthase, which is an essential enzyme in the obligate aerobic Mycobacterium genus, but how it binds the intact enzyme is unknown. Here we determined cryo-electron microscopy structures of M. smegmatis ATP synthase alone and in complex with bedaquiline. The drug-free structure suggests that hook-like extensions from the α-subunits prevent the enzyme from running in reverse, inhibiting ATP hydrolysis and preserving energy in hypoxic conditions. Bedaquiline binding induces large conformational changes in the ATP synthase, creating tight binding pockets at the interface of subunits a and c that explain the potency of this drug as an antibiotic for tuberculosis.

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.
