The Domain Structure of Sigma 54 as Determined by Analysis of a Set of Deletion Mutants

Escherichia coli σ54 was analyzed by making a series of 16 internal deletions within its gene and analyzing the properties of the mutant proteins. All of the mutant proteins except one were strongly defective in a growth test that relied on σ54 function. Additional assays were applied to determine t...
