structure of the mutant Catabolite gene activator protein V140A

Template:ABSTRACT PUBMED 24058293

Function

[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]

About this Structure

4i02 is a 6 chain structure with sequence from Escherichia coli k-12. Full crystallographic information is available from OCA.
