Expression and regulation

• Operon:
  • cggR-gapA-pgk-tpiA-pgm-eno
  • cggR-gapA

The primary mRNAs of the operon are highly unstable. The primary mRNA is subject to processing at the very end of the cggR open reading frame. This results in stable mature gapA and gapA-pgk-tpiA-pgm-eno mRNAs. The processing event requires the Rny protein.

• Sigma factor: SigA

• Regulation: CggR represses the operon in the absence of glycolytic sugars

• Regulatory mechanism: repression

• Database entries: DBTBS
