Abstract

In prokaryotes, RuvA, RuvB, and RuvC process the universal DNA intermediate of homologous recombination, termed Holliday junction. The tetrameric DNA helicase RuvA specifically binds to the Holliday junction and facilitates the isomerization of the junction from the stacked folded configuration to the square-planar structure [PubMed12408833]. In the RuvA tetramer, each subunit consists of three domains, I, II and III, where I and II form the major core that is responsible for Holliday junction binding and base pair rearrangements of Holliday junction executed at the crossover point, whereas domain III regulates branch migration through direct contact with RuvB.

The domain represents the C-terminal domain III of RuvA. This domain plays a significant role in the ATP-dependent branch migration of the hetero-duplex through direct contact with RuvB [PubMed10890893]. Within the Holliday junction, this domain makes no interaction with the DNA.

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 3 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 DNA helicase RuvA subunit, C-terminal domain 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 3 hidden Markov models representing the DNA helicase RuvA subunit, C-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
