The effect of dam methylation on the expression of glnS in E. coli
1Department of Molecular Biophysics and Biochemistry, Yale University, New Haven, CT 06511.
Abstract:
The wild type glnS promoter contains a dam methylation site. In dam strains, the expression of glnS is enhanced 2.6-fold. A mutated form of the promoter has been isolated in which the dam methylation site is lost. Expression of this promoter is insensitive to dam methylation.
