Histidine kinase-like ATPase domain of the B subunit of DNA gyrase; This family includes histidine kinase-like ATPase domain of the B subunit of DNA gyrase. Bacterial DNA gyrase is a type II topoisomerase (type II as it transiently cleaves both strands of DNA) which catalyzes the introduction of negative supercoils into DNA, possibly by a mechanism in which one segment of the double-stranded DNA substrate is passed through a transient break in a second segment. It consists of GyrA and GyrB subunits in an A2B2 stoichiometry; GyrA subunits catalyze strand-breakage and reunion reactions, and GyrB subunits hydrolyze ATP. DNA gyrase is found in bacteria, plants and archaea, but as it is absent in humans it is a possible drug target for the treatment of bacterial and parasite infections.

DNA topoisomerase IV, B subunit, proteobacterial; Operationally, topoisomerase IV is a type II topoisomerase required for the decatenation of chromosome segregation. Not every bacterium has both a topo II and a topo IV. The topo IV families of the Gram-positive bacteria and the Gram-negative bacteria appear not to represent a single clade among the type II topoisomerases, and are represented by separate models for this reason. This protein is active as an alpha(2)beta(2) heterotetramer. [DNA metabolism, DNA replication, recombination, and repair]

Histidine kinase-like ATPase domain; This superfamily includes the histidine kinase-like ATPase (HATPase) domains of several ATP-binding proteins such as histidine kinase, DNA gyrase B, topoisomerases, heat shock protein 90 (HSP90), phytochrome-like ATPases and DNA mismatch repair proteins. Domains belonging to this superfamily are also referred to as GHKL (gyrase, heat-shock protein 90, histidine kinase, MutL) ATPase domains.

Histidine kinase-like ATPase domain of DNA mismatch repair proteins Escherichia coli MutL, human MutL homologs (MLH/ PMS), and related domains; This family includes the histidine kinase-like ATPase (HATPase) domains of Escherichia coli MutL, human MLH1 (mutL homolog 1), human PMS1 (PMS1 homolog 1, mismatch repair system component), human MLH3 (mutL homolog 3), and human PMS2 (PMS1 homolog 2, mismatch repair system component). MutL homologs (MLH/PMS) participate in MMR (DNA mismatch repair), and in addition have role(s) in DNA damage signaling and suppression of homologous recombination (recombination between partially homologous parental DNAs). The primary role of MutL in MMR is to mediate protein-protein interactions during mismatch recognition and strand removal; a ternary complex is formed between MutS, MutL, and the mismatched DNA, which activates the MutH endonuclease.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
