=The gene=
=== Basic information ===
* '''Locus tag:''' BSU37790
===Phenotypes of a mutant ===
Poor growth on complex media such as SP (sporulation medium). No growth in minimal media with arginine as the only carbon source. Rapid accumulation of suppressor mutants ([[gudB |''gudB1'']])
=== Database entries ===
* '''DBTBS entry:''' [http://dbtbs.hgc.jp/COG/prom/rocG.html]
* '''SubtiList entry:''' [http://genolist.pasteur.fr/SubtiList/genome.cgi?gene_detail+BG10621]
=== Additional information===
=The protein=
=== Basic information/ Evolution ===
* '''Catalyzed reaction/ biological activity:''' L-glutamate + H<sub>2</sub>O + NAD<sup>+</sup> = 2-oxoglutarate + NH<sub>3</sub> + NADH (according to Swiss-Prot) L-glutamate + H(2)O + NAD(+) = 2-oxoglutarate + NH(3) + NADH, controls the activity of the [[GltC]] transcription activator [http://www.ncbi.nlm.nih.gov/sites/entrez/17608797 PubMed]
* '''Protein family:''' Glu/Leu/Phe/Val dehydrogenases family (according to Swiss-Prot) Glu/Leu/Phe/Val dehydrogenases family
* '''Paralogous protein(s):''' [[GudB]]
=== Extended information on the protein ===
* '''Kinetic information:'''
* '''Domains:'''
* '''Modification:'''
* '''Cofactor(s):'''
* '''Effectors of protein activity:'''
* '''Interactions:''' RocG-[[GltC]], this interaction prevents transcription activation of the ''[[gltA]]-[[gltB]]'' operon by GltC [http://www.ncbi.nlm.nih.gov/sites/entrez/17608797 PubMed]
* '''Localization:'''
=== Database entries ===
* '''Structure:'''

* '''E.C. number:''' [http://www.expasy.org/enzyme/1.4.1.2 1.4.1.2]  1.4.1.2]
=== Additional information===
=Expression and regulation=
* '''Operon:''' ''rocG''
* '''Sigma factor:''' [[SigL]] [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=+10468601 PubMed]
* '''Regulation:''' induced by arginine ([[RocR]], [[AhrC]]), ornithine or proline, subject to carbon catabolite repression ([[CcpA]])
* '''Regulatory mechanism:''' [[RocR]]: transcription activation [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=+12634342 PubMed][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=+10468601 PubMed]; [[AhrC]]: transcription activation ; [[CcpA]]: transcription repression
* '''Additional information:'''
Activation by [[RocR]] requires binding of RocG to a downstream element [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=+12634342 PubMed]
