Figure 1. Heat-Shock Promoter Governing Expression of the Heat-Shock Gene ibpA in Buchnera .

Figure 1

(A) Schematic of regulation of ibpA expression showing position of heat-shock promoter.

(B) Sequence of E. coli consensus heat-shock promoter and of all heat-shock promoters of Buchnera of S. graminum and of A. pisum. Sequences from published complete genome data were confirmed for both species. The only variant is the ibpA promoter allele, which has a shorter spacer length, resulting in almost complete loss of the heat-shock response of ibpA.
