  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification: the mature SKF is cyclic 26-amino acid peptide that is posttranslationally modified with one disulfide and one cysteine thioether bridged to the alpha-position of a methionine PubMed

Database entries

  • Structure:
  • KEGG entry: [3]
  • E.C. number:

Additional information

Expression and regulation

  • Regulation:
    • repressed by glucose (33-fold) PubMed
    • expressed under conditions that trigger sporulation (Spo0A) PubMed
    • repressed during logrithmic growth (AbrB) PubMed
    • induced by phosphate starvation (PhoP) PubMed
    • induced by rhamnogalacturonan 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-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

Biological materials

  • Mutant:
  • Expression vector:
  • lacZ fusion:
  • GFP fusion:
  • two-hybrid system:
  • Antibody:
