The protein
Basic information/ Evolution

Additional information
GAP dehydrogenases from different sources (incl. Geobacillus stearothermophilus) were shown to cleave RNA (PubMed). Moreover, mutations in gapA from B. subtilis can suppress mutations in genes involved in DNA replication (PubMed).
Expression and regulation
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. PubMed The processing event requires the Rny protein.
- Database entries: DBTBS
- Additional information: GapA is one of the most abundant proteins in the cell. In the presence of glucose, there are about 25,000 GapA molecules per cell (PubMed).
