Additional information
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity: D-glyceraldehyde 3-phosphate + phosphate + NAD+ = 3-phospho-D-glyceroyl phosphate + NADH (according to Swiss-Prot)
- This reaction is part of the glycolysis.
- Protein family: glyceraldehyde-3-phosphate dehydrogenase family (according to Swiss-Prot)
- Paralogous protein(s): GapB
Extended information on the protein

- Domains:
- Modification:
- Cofactor(s): NAD+ (do not accept NADP+) PubMed
- Effectors of protein activity:
- Interactions:
- GapA-PtsH: HPr(Ser-46-P) binds GapA resulting in a slight inhibition of enzymatic activity PubMed

- E.C. number: 1.2.1.12
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. The processing event requires the Rny protein.
- Sigma factor: SigA
- Regulation: expression activated by glucose (10 fold) PubMed, CggR represses the operon in the absence of glycolytic sugars PubMed
- Regulatory mechanism: repression
- 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).
Biological materials
- Mutant: essential
- Expression vector:
- GFP fusion:
- two-hybrid system: B. pertussis adenylate cyclase-based bacterial two hybrid system (BACTH), available in Stülke lab
- Antibody: available in Stülke lab
