N-acetylmuramic acid 6-phosphate etherase; This protein, MurQ, is involved in recycling components of the bacterial murein sacculus turned over during cell growth. The cell wall metabolite anhydro-N-acetylmuramic acid (anhMurNAc) is converted by a kinase, AnmK, to MurNAc-phosphate, then converted to N-acetylglucosamine-phosphate by this etherase, called MurQ. This family of proteins is similar to the C-terminal half of a number of vertebrate glucokinase regulator proteins and contains a Prosite pattern which is shared by this group of proteins in a region of local similarity.

RpiR-like protein. RpiR contains a SIS (Sugar ISomerase) domain, which is found in many phosphosugar isomerases and phosphosugar binding proteins. In E. coli, rpiR negatively regulates the expression of rpiB gene. Both rpiB and rpiA are ribose phosphate isomerases that catalyze the reversible reactions of ribose 5-phosphate into ribulose 5-phosphate.

2.12e-03
Hexulose-6-phosphate isomerase (PHI). PHI is a member of the SIS (Sugar ISomerase domain) superfamily. In the ribulose monophosphate pathway of formaldehyde fixation, hexulose-6-phosphate synthase catalyzes the condensation of ribulose-5-phosphate with formadelhyde to become hexulose-6-phosphate, which is then isomerized to fructose-6-phosphate by PHI.

SIS (Sugar ISomerase) domain repeat 1 found in Glucosamine 6-phosphate synthase (GlmS) and Glucosamine-6-phosphate deaminase (GlmD). The SIS domain is found in many phosphosugar isomerases and phosphosugar binding proteins. GlmS contains a N-terminal glutaminase domain and two C-terminal SIS domains and catalyzes the first step in hexosamine metabolism, converting fructose 6-phosphate into glucosamine 6-phosphate using glutamine as nitrogen source. The glutaminase domain hydrolyzes glutamine to glutamate and ammonia. Ammonia is transferred through a channel to the isomerase domain for glucosamine 6-phosphate synthesis. The end product of the pathway is N-acetylglucosamine, which plays multiple roles in eukaryotic cells including being a building block of bacterial and fungal cell walls. In the absence of glutamine, GlmS catalyzes the isomerization of fructose 6-phosphate into glucose 6- phosphate (PGI-like activity). Glucosamine-6-phosphate deaminase (GlmD) contains two SIS domains and catalyzes the deamination and isomerization of glucosamine-6-phosphate into fructose-6-phosphate with the release of ammonia; in presence of high ammonia concentration, GlmD can catalyze the reverse reaction.

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.
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,

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
