Abstract excerpt
Conversion of Esigma(54) closed promoter complexes to open promoter complexes requires specialized activators which are members of the AAA (ATPases Associated with various cellular Activities) protein family. The ATP binding and hydrolysis activity of Esigma(54) activators is used in an energy coupling reaction to remodel the Esigma(54) closed promoter complex and to overcome the sigma(54)-imposed block on open...
