Abstract excerpt
The cadA gene that encodes lysine decarboxylase in Escherichia coli is induced by low pH and - during anaerobic growth - by the substrate, lysine. We used operon fusions of cadA to lacZ to investigate the effects of aeration on cadA regulation. When an insertion mutation in osmZ (= hns) was introduced, a cadA-lacZ fusion was derepressed in the presence of air to approximately the same level as seen during...
