Title: Structural basis of promoter recognition by Staphylococcus aureus RNA polymerase.
Authors: Linggang Yuan / Qingyang Liu / Liqiao Xu / Bing Wu / Yu Feng /
Abstract: Bacterial RNAP needs to form holoenzyme with σ factors to initiate transcription. While Staphylococcus aureus σ controls housekeeping functions, S. aureus σ regulates virulence, biofilm formation, ...Bacterial RNAP needs to form holoenzyme with σ factors to initiate transcription. While Staphylococcus aureus σ controls housekeeping functions, S. aureus σ regulates virulence, biofilm formation, persistence, cell internalization, membrane transport, and antimicrobial resistance. Besides the sequence difference, the spacers between the -35 element and -10 element of σ regulated promoters are shorter than those of σ regulated promoters. Therefore, how σ recognizes and initiates transcription from target promoters can not be inferred from that of the well studied σ. Here, we report the cryo-EM structures of S. aureus RNAP-promoter open complexes comprising σ and σ, respectively. Structural analyses, in combination with biochemical experiments, reveal the structural basis for the promoter specificity of S. aureus transcription. Although the -10 element of σ regulated promoters is recognized by domain σ as single-stranded DNA, the -10 element of σ regulated promoters is co-recognized by domains σ and σ as double-stranded DNA, accounting for the short spacers of σ regulated promoters. S. aureus RNAP is a validated target of antibiotics, and our structures pave the way for rational drug design targeting S. aureus RNAP.

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.
