Disease relevance of UTI89_C1284

  • The fourth nucleotide of the loop extrudes from the GNRA fold to enable the E. coli elongation factor NusA to recognize the N protein/RNA complex [1].
  • As a transcriptional activator, the N protein of phage lambda acts to suppress transcription termination by recognizing a promoter-proximal site, nut, which is separated from the terminators by thousands of base pairs [2].
  • In this study, recombinant SARS-CoV N protein was shown to be dimeric by analytical ultracentrifugation, size exclusion chromatography coupled with light scattering, and chemical cross-linking [3].
  • These results suggest that the N protein oligomerization involves the C-terminal residues 285-422, and this region is a good target for mutagenic studies to disrupt N protein self-association and virion assembly [3].
  • We have purified the Rhodobacter capsulatus sigma N protein, which is distinctive in lacking an acidic region implicated in the melting of promoter DNA by the Escherichia coll sigma N holoenzyme, and may represent a minor subclass of sigma N proteins [4].
