Function

[RPOA_ECOLI] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme.[HAMAP-Rule:MF_00059] [CRP_ECOLI] This protein complexes with cyclic AMP and binds to specific DNA sites near the promoter to regulate the transcription of several catabolite-sensitive operons. The protein induces a severe bend in the DNA. Acts as a negative regulator of its own synthesis as well as for adenylate cyclase (cyaA), which generates cAMP.^[1]

Publication Abstract from PubMed

The Escherichia coli catabolite activator protein (CAP) activates transcription at P(lac), P(gal), and other promoters through interactions with the RNA polymerase alpha subunit carboxyl-terminal domain (alphaCTD). We determined the crystal structure of the CAP-alphaCTD-DNA complex at a resolution of 3.1 angstroms. CAP makes direct protein-protein interactions with alphaCTD, and alphaCTD makes direct protein-DNA interactions with the DNA segment adjacent to the DNA site for CAP. There are no large-scale conformational changes in CAP and alphaCTD, and the interface between CAP and alphaCTD is small. These findings are consistent with the proposal that activation involves a simple "recruitment" mechanism.
