We have constructed promoter probe vectors with the Escherichia coli galactokinase monitoring system that can be used in Bacillus subtilis. In vivo studies with these vectors demonstrated that the E. coli trp and tac(trp::lac) promoter regions could be utilized in B. subtilis. These promoter regions and the promoter region for the erythromycin resistance gene originating from Staphylococcus aureus were preferentially utilized during the stationary growth phase of B. subtilis, whereas the B. subtilis P21K and P29K promoters were utilized during the exponential growth phase and decreased rapidly during the stationary phase. The apparent strength of these promoters of E. coli in B. subtilis, in terms of galactokinase units, was comparable with those of the B. subtilis promoters. [ABSTRACT FROM AUTHOR] |
