Expression and regulation

• Operon: capB-capC-capA-capE PubMed

• Expression browser: capA PubMed

• Sigma factor: SigA PubMed

• Regulation:

• Regulatory mechanism: activated by DegU-P PubMed

• Additional information:
  • The operon is not expressed in the lab strain 168 due to lack of expression of DegQ resulting in inactivity of DegS and DegU PubMed
  • expression of the operon is increased in motA or motB mutants due to increased DegU phosphorylation PubMed
