DNA binding
... For the lac operon, gene expression is maximal when the binding of allolactose relieves the inhibition by the lac repressor and the CAP–cAMP complex stimulates the binding of RNA polymerase. It shows a concerted regulation of gene expression. There are four possibilities of coregulation of CAP and L ...
