Methyl-accepting chemotaxis protein (MCP), signaling domain; Methyl-accepting chemotaxis proteins (MCPs or chemotaxis receptors) are an integral part of the transmembrane protein complex that controls bacterial chemotaxis, together with the histidine kinase CheA, the receptor-coupling protein CheW, receptor-modification enzymes, and localized phosphatases. MCPs contain a four helix trans membrane region, an N-terminal periplasmic ligand binding domain, and a C-terminal HAMP domain followed by a cytoplasmic signaling domain. This C-terminal signaling domain dimerizes into a four-helix bundle and interacts with CheA through the adaptor protein CheW.

Four helix bundle sensory module for signal transduction; This family is a four helix bundle that operates as a ubiquitous sensory module in prokaryotic signal-transduction. The 4HB_MCP is always found between two predicted transmembrane helices indicating that it detects only extracellular signals. In many cases the domain is associated with a cytoplasmic HAMP domain suggesting that most proteins carrying the bundle might share the mechanism of transmembrane signalling which is well-characterized in E coli chemoreceptors. This domain recognizes citrate and TCA cycle intermediates, cis-aconitate, boric acid, Phenanthrene, pyrene and benzopyrene (Matilla et el., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

ligand-binding sensor domain of Comamonas testosteroni CNB-2 MCP2201 and similar chemoreceptors; This family includes the ligand-binding sensor domain of Comamonas testosteroni transmembrane chemoreceptor CNB-2 MCP2201 and similar chemoreceptors. The C. testosteroni methyl-accepting chemotaxis protein MCP2201 triggers chemotaxis towards tricarboxylic acid cycle intermediates such as citric acid and aromatic compounds. While the apo-form ligand binding domain (LBD) forms a typical four-helix bundle homodimer, similar to other chemoreceptors in the superfamily such as Escherichia coli Tar and Tsr, the citrate-bound LBD reveals a four-helix bundle homotrimer. This type of oligomerization has never been observed in other bacterial chemoreceptor LBD. Site-directed mutations of key amino acid residues have demonstrated the physiological importance of the homotrimer for chemotaxis.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

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.

(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
