Transcription unit          
Name: hdeAB-yhiD
Gene(s): yhiD, hdeB, hdeA   Genome Browser M3D Gene expression COLOMBOS
Note(s): The hdeAB-yhiD operon is induced under stationary phase Shin M,2005. Weber H,2005 and at acid pH Hayes ET,2006. Tucker DL,2003. Marzan LW,2013 in a RcsB-dependent manner Johnson MD,2011
Lrp represses the hdeAB-yhiD operon only in the exponential phase at pH 7.0, and MarA reduces this repression Ruiz C,2008.
The hdeAB genes are upregulated by long-term (8 to 12 h) exposure of E. coli to some biocides Merchel Piovesan Pereira B, Wang X, Tagkopoulos I,2020.
Indole enhances the expression of several genes related to acid resistance, such as gadA, gadB, gadC, hdeA, hdeB, hdeD, slp, and gadE Hirakawa H, Hayashi-Nishino M, Yamaguchi A, Nishino K,2010 The acid resistance phenotype induced by indoles is mainly due to increased expression of the glutamine decarboxylase system Hirakawa H, Hayashi-Nishino M, Yamaguchi A, Nishino K,2010
The mdtEF-tolC, malEFG, gadBC, treBC, entCEBA-ybdB, hdeAB-yhiD, and alaE operons were differentially regulated after induction of the nonnative organic acid citramalate Webb J,2019
The expression of hdeB appears to be slightly repressed by Rob under butanol stress Wang Z,2020.

Note(s): The same transcriptional start site for this promoter is used in hns rpoS mutant strains as well as strains wild type for H-NS and σ38. This indicates that the same promoter can be utilized by both σ38 and σ70 in vivo. This promoter has significant homology to the consensus of a σ70 promoter even though it is dependent upon σ38 Arnqvist A,1994.
