Operon      
Name: rprA
This page displays every known transcription unit of this operon and their known regulation.


Transcription unit          
Name: rprA
Gene(s): rprA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The expression of the gene rprA is increased when colicin (at 30 ng/ml) is added to the medium 23421615. RcsB regulates rprA transcription by both phosphorylation and acetylation. RcsBs phosphorylation and control of rprA transcription requires acetyl-phosphate (AcP) as the group donor. RcsB isolated from ackA or cob mutants is hyperacetylated, and this hyperacetylation inhibits RcsB activity through the acetylation of Lys-154, which plays an important role in rprA regulation 23852870 This is the first report that in vivo acetylation by multiple lysines of a bacterial transcription factor regulates its activity 23852870
rprA is induced under biofilm conditions 30131361
