Sugar-binding N-terminal domain; This is the N-terminal domain found in proteins in a range of Proteobacteria as well as the Gram-positive Oceanobacillus iheyensis. Structural analysis of the whole protein indicates the N- and C-termini act together to produce a surface into which a threonate-ADP complex is bound, demonstrating that a sugar binding site is on the N-terminal domain, and a nucleotide binding site is in the C-terminal domain. There is a critical motif, DDXTG, at approximately residues 22-25. Proteins containing this domain have been predicted as kinases. Some members are associated with PdxA2 by physical clustering and gene fusion with PdxA2. Some members that are fused with PdxA2 have been shown to be involved in L-4-hydroxythreonine (4HT) phosphorylation, part of the alternative pathway to make PLP (pyridoxal 5'-phosphate) out of a toxic metabolite, 4HT. However, 4HT phosphorylation might not be the main function of this group of proteins. Moreover, some members that are not associated with pdxA2, and even one that is associated with pdxA2, have lost 4HT kinase activity. Functional analysis demonstrate that family members include D-Threonate kinases (DtnK), D-Erythronate kinases (DenK) and 3-Oxo-tetronate kinases (OtnK).

PTS system, glucitol/sorbitol-specific, IIBC component; Bacterial PTS transporters transport and concomitantly phosphorylate their sugar substrates, and typically consist of multiple subunits or protein domains. The Gut family consists only of glucitol-specific permeases, but these occur both in Gram-negative and Gram-positive bacteria.E. coli consists of IIA protein, a IIC protein and a IIBC protein. This family is specific for the IIBC component. [Transport and binding proteins, Carbohydrates, organic alcohols, and acids, Signal transduction, PTS]

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.

(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
