STRUCTURE OF BACTERIOPHAGE LAMBDA CII protein

Structural highlights

1zpq is a 4 chain structure with sequence from Bacteriophage lambda. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	CII (Bacteriophage lambda)
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

[RPC2_LAMBD] This protein and protein CIII form a complex that is involved in the initiation of lysogeny. The complex binds at either of the cy regulatory sites preceding the CI repressor protein and integrase coding regions and induces transcription of these genes.

Evolutionary Conservation

Publication Abstract from PubMed

The tetrameric cII protein from bacteriophage lambda activates transcription from the phage promoters P(RE), P(I), and P(AQ) by binding to two direct repeats that flank the promoter -35 element. Here, we present the X-ray crystal structure of cII alone (2.8 A resolution) and in complex with its DNA operator from P(RE) (1.7 A resolution). The structures provide a basis for modeling of the activation complex with the RNA polymerase holoenzyme, and point to the key role for the RNA polymerase alpha subunit C-terminal domain (alphaCTD) in cII-dependent activation, which forms a bridge of protein/protein interactions between cII and the RNA polymerase sigma subunit. The model makes specific predictions for protein/protein interactions between cII and alphaCTD, and between alphaCTD and sigma, which are supported by previous genetic studies.
