Expression and regulation

  • Regulation: repressed by glucose (33-fold) PubMed
    • expressed under conditions that trigger sporulation (Spo0A) PubMed
    • repressed during logrithmic growth (AbrB) PubMed
  • Additional information:
    • Northern blotting during during phosphate limitation showed an intense 0.25 kb skfA-specific transcript, and a weaker 6.5 kb skfA-skfB-skfC-skfD-skfE-skfF-skfG-skfH transcript.
    • The skfA transcript is stabilized by a stem-loop structure in the skfA-skfB intergenic region. PubMed
    • The mRNA is very stable (half-life > 15 min) PubMed
