Escherichia coli K-12 substr. MG1655 Pathway: EvgSA Two-Component Signal Transduction System

Diagram Key: ?

Genetic Regulation Schematic: ?

Superclasses: Signal transduction pathways

Summary:
The EvgSA two component signal transduction system (TCS) comprises EvgS - the membrane associated sensor kinase - and EvgA - the cytoplasmic response regulator. The EvgSA TCS is believed to initiate a complex transcriptional cascade that functions for acid and drug resistance in E.coli [Itou09]. Activation of the EvgSA system occurs under mild acidic conditions (pH 5-6) and in the presence of high concentrations of alkali metals [Eguchi14].

Activation of the EvgSA signal transduction system (through use of a constitutively active EvgS mutant) directly upregulates at least six genes/operons including the transcriptional regulator ydeO which then upregulates gadE - the master regulator of acid resistance genes [Itou09].

EvgS is a member of the 'unorthodox' sensor kinase class where a multistep phosphorelay occurs between alternating histidine and aspartate residues before the EvgA response regulator is activated [Appleby96]

Interaction between the EvgSA and PhoQP two-component systems has been observed in E.coli and is mediated by the small protein B1500 [Eguchi04, Eguchi07, Eguchi08].
