Escherichia coli K-12 substr. MG1655 Polypeptide: GlrR DNA-binding transcriptional activator



Gene: glrR Accession Numbers: EG11285 (EcoCyc), b2554, ECK2551

Synonyms: yfhA, GlrR response regulator

Regulation Summary Diagram: ?

Alternative forms of GlrR DNA-binding transcriptional activator: GlrR-Pasp56 DNA binding transcriptional activator

Summary:
GlrR is the response regulator of the two-component GlrKR signal transduction system [Reichenbach09]. GlrR contains a σ54 interaction domain which binds to a DNA region located more than 100bp upstream of glmY. Transcription of a glmY-lacZ fusion from the σ54 promoter is abolished in a GlrR null strain. Purified GlrR can be phosphorylated in vitro by the cognate histidine kinase GlrK as well as by the non-cognate histidine kinases UhpB, RstB, and BaeS [Yamamoto05].
