Cross talk to the phosphate regulon of Escherichia coli by PhoM protein: PhoM is a histidine protein kinase and catalyzes phosphorylation of PhoB and PhoM-open reading frame 2.

Abstract excerpt

Transcription of the genes in the phosphate regulon in Escherichia coli is activated by PhoB protein, which is phosphorylated by PhoR protein under phosphate-limiting conditions. In the absence of the phoR function, the genes in the phosphate regulon are expressed constitutively and the expression is dependent on the function of phoM and phoB. We constructed a plasmid with a lacZ'-'phoM fusion gene, which encoded...
