Expression and regulation

• Operon: alsS-alsD PubMed

• Sigma factor: SigA PubMed

• 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: repression in the absence of acetate PubMed, Rex: transcription repression if the ratio NADH2/NAD is high PubMed
