Expression and regulation

• Operon: cotA PubMed

• Expression browser: cotA PubMed

• Sigma factor: SigK PubMed

• Regulation:
  • expressed late during sporulation in the mother cell (SigK, GerE) PubMed

• Regulatory mechanism:
  • GerE: transcription repression PubMed

• Additional information:
  • translation is likely to require Efp due to the presence of several consecutive proline residues PubMed
