flagellar motor switch protein FliM; Members of this family are the flagellar motor switch protein FliM. The family excludes FliM homologs that lack an N-terminal region critical to interaction with phosphorylated CheY. One set lacking this N-terminal region is found in Rhizobium meliloti, in which the direction of flagellar rotation is not reversible (i.e. the FliM homolog does not act to reverse the motor direction), and in related species. Another is found in Buchnera, an obligate intracellular endosymbiont with genes for many of the components of the flagellar apparatus, but not, apparently, for flagellin iself.

flagellar protein FliM; This family contains bacterial flagellar protein FliM which is localized in the flagellar switch complex along with FliG and FliY; all are present in many copies, and together they correspond structurally to the C-ring of the flagellar basal body. FliM does not contain the CheC consensus sequence of the phosphatase active site ([DS]xxxExxNx(22)P) and is not a CheY-P phosphatase. FliM sits in the center of the rotor with the N-terminal region interacting with the signaling protein, phosphorylated CheY (CheY-P). The activated form of CheY destabilizes the parallel arrangement of FliM molecules, and perturbs FliG alignment in a process that may reflect the onset of rotation switching. This suggests a model of C-ring assembly in which intermolecular contacts among FliG domains provide a template for FliM assembly. Recent data show that binding of FliM to spermine synthase, SpeE, contributes to flagellar motility, an association that is unique to Helicobacter species.

of the residues that compose this conserved feature have been mapped to the query sequence.
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.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

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
multi-domain models that were computationally detected and are likely to contain multiple single domains
