Title: Structural basis for transcription inhibition by E. coli SspA.

Abstract: Stringent starvation protein A (SspA) is an RNA polymerase (RNAP)-associated protein involved in nucleotide metabolism, acid tolerance and virulence of bacteria. Despite extensive biochemical and ...Stringent starvation protein A (SspA) is an RNA polymerase (RNAP)-associated protein involved in nucleotide metabolism, acid tolerance and virulence of bacteria. Despite extensive biochemical and genetic analyses, the precise regulatory role of SspA in transcription is still unknown, in part, because of a lack of structural information for bacterial RNAP in complex with SspA. Here, we report a 3.68 Å cryo-EM structure of an Escherichia coli RNAP-promoter open complex (RPo) with SspA. Unexpectedly, the structure reveals that SspA binds to the E. coli σ70-RNAP holoenzyme as a homodimer, interacting with σ70 region 4 and the zinc binding domain of EcoRNAP β' subunit simultaneously. Results from fluorescent polarization assays indicate the specific interactions between SspA and σ70 region 4 confer its σ selectivity, thereby avoiding its interactions with σs or other alternative σ factors. In addition, results from in vitro transcription assays verify that SspA inhibits transcription probably through suppressing promoter escape. Together, the results here provide a foundation for understanding the unique physiological function of SspA in transcription regulation in bacteria.

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.

Yorodumi

Thousand views of thousand structures

  • Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
  • This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
  • The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
