RegulonDB RegulonDB 10.10: Operon Form
   

spy operon and associated TUs in Escherichia coli K-12 genome




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


Transcription unit          
Name: spy
Gene(s): spy   Genome Browser M3D Gene expression COLOMBOS
Note(s): spy gene expression is induced separately by both copper and zinc metals through the CpxAR and BaeSR sensor response regulatory systems, respectively. BaeR can be the primary regulator and CpxR can enhance its function Yamamoto K,2008. Srivastava SK, Lambadi PR, Ghosh T, Pathania R, Navani NK,2014 On the other hand, BaeR is the primary regulator of spy in the presence of the protein-unfolding agent ethanol Srivastava SK, Lambadi PR, Ghosh T, Pathania R, Navani NK,2014
The expression of the gene spy is increased when colicin (at 30 ng/ml) is added to the medium Kamen?ek S, ?gur-Bertok D,2013. spy is also induced by indole Hirakawa H,2005. Raffa RG,2002.
Under conditions leading to NlpE outer membrane lipoprotein overexpression, the transcription of the spy gene is increased by CpxR Raivio TL,2013
The spy gene is upregulated by long-term (8 to 12 h) exposure of E. coli to some biocides Merchel Piovesan Pereira B, Wang X, Tagkopoulos I,2020.
