Extended information on the protein

  • Kinetic information:
  • Domains:
    • transmembrane domain (aa 5–24) PubMed
    • coiled-coiled domain (may form a leucine zipper) (aa 30-150) PubMed
    • KH domain (aa 210–280) PubMed
    • HD domain (aa 330–430) PubMed
    • C-terminal domain (aa 430-520) PubMed
  • Modification:
  • Cofactor(s): requires Mg+2, which can be replaced by Zn+2 or Mn+2 ions, PubMed
  • Effectors of protein activity: appears sensitive to downstream secondary structure, PubMed

  • KEGG entry: [3]

Additional information

required for the processing of the gapA operon mRNA

Expression and regulation

  • Regulation: constitutive
  • Regulatory mechanism:
  • Additional information:
    • there is a terminator between rny and ymdB, most transcripts terminate there PubMed
    • The mRNA has a long 5' leader region. This may indicate RNA-based regulation PubMed
