GAP dehydrogenases from different sources (incl. ''Geobacillus stearothermophilus'') were shown to cleave RNA ([http://www.ncbi.nlm.nih.gov/sites/entrez/12359717 PubMed]). Moreover, mutations in ''gapA'' from ''B. subtilis'' can suppress mutations in genes involved in DNA replication ([http://www.ncbi.nlm.nih.gov/sites/entrez/17505547 PubMed]).
 
 
=Expression and regulation=
 
 
* '''Operon:'''
 
** ''[[cggR]]-[[gapA]]-[[pgk]]-[[tpi]]-[[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 [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=+12622823 PubMed]
 
 
* '''Regulatory mechanism:''' repression
 
 
* '''Database entries:''' [http://dbtbs.hgc.jp/COG/prom/cggR-gapA-pgk-tpiA-pgm-eno.html 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 ([http://www.ncbi.nlm.nih.gov/sites/entrez/12634343 PubMed]).
