Abstract

Bacteriophage lambda C1 repressor controls the expression of viral genes as part of the lysogeny/lytic growth switch. C1 is essential for maintaining lysogeny, where the phage replicates non-disruptively along with the host. If the host cell is threatened, then lytic growth is induced. The Lambda C1 repressor consists of two domains connected by a linker: an N-terminal DNA-binding domain that also mediates interactions with RNA polymerase, and a C-terminal dimerisation domain [PubMed10892750]. The DNA-binding domain consists of four helices in a closed folded leaf motif. Several different phage repressors from different helix-turn-helix families contain DNA-binding domains that adopt a similar topology. These include the Lambda Cro repressor, Bacteriophage 434 C1 and Cro repressors, P22 C2 repressor, and Bacteriophage Mu Ner protein.

The DNA-binding domain of Bacillus subtilis spore inhibition repressor SinR is identical to that of phage repressors [PubMed9799632]. SinR represses sporulation, which only occurs in response to adverse conditions. This provides a possible evolutionary link between the two adaptive responses of bacterial sporulation and prophage induction.

Other DNA-binding domains also display similar structural folds to that of Lambda C1. These include bacterial regulators such as the purine repressor (PurR), the lactose repressor (Lacr) and the fructose repressor (FruR), each of which has an N-terminal DNA-binding domain that exhibits a fold similar to that of lambda C1, except that they lack the first helix [PubMed7973627, PubMed10700279, PubMed9237914]. POU-specific domains found in transcription factors such as in Oct-1, Pit-1 and Hepatocyte nuclear factor 1a (LFB1/HNF1) display four-helical fold DNA-binding domains similar to that of Lambda C1 [PubMed11583619, PubMed9009203, PubMed12453420]. The N-terminal domain of cyanase has an alpha-helix bundle motif similar to Lambda C1, but it probably does not bind DNA. Cyanase is an enzyme found in bacteria and plants that catalyses the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide in response to extracellular cyanate [PubMed10801492].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 45 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a lambda repressor-like DNA-binding domains domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 45 hidden Markov models representing the lambda repressor-like DNA-binding domains superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
