Additional information
Expression and regulation
- Regulation: induction by acetate (AlsR) PubMed, repressed as long as terminal electron acceptors are available for respiration (Rex) PubMed
Note: since acetate formation requires ackA activation by CcpA there is an indirect effect of CcpA on the alsSD operon: the operon is not expressed in ccpA mutants
- Regulatory mechanism: AlsR: transcription activation in the presence of acetate PubMed, Rex: transcription repression if the ratio NADH2/NAD is high PubMed
- Additional information:

- Expression vector:
- lacZ fusion:
- GFP fusion:
- two-hybrid system:
