D-tagatose-1,6-bisphosphate aldolase subunit GatZ/KbaZ-like; Escherichia coli and other enteric bacteria contain two closely related D-tagatose 1,6-bisphosphate (TagBP)-specific aldolases involved in catabolism of galactitol (genes gatY gatZ) and of N-acetyl-galactosamine and D-galactosamine (genes kbaY, kbaZ, also called agaY, agaZ). The catalytic subunits GatY/KbaY alone are sufficient to show aldolase activity and contain most or all of the residues that have been identified as essential in substrate/product recognition and catalysis for class II aldolases. However, these aldolases differ from other Class II aldolases (which are homodimeric enzymes) in that they require subunits GatZ/KbaZ for full activity and for good in vivo and in vitro stability. The Z subunits alone do not show any aldolase activity. This entry represents GatZ and KbaZ subunits. This entry also includes the D-tagatose 6-phosphate 4-epimerase Atu3167 from Agrobacterium fabrum which catalyzes the epimerization of D-tagatose 6-phosphate to D-fructose 6-phosphate. It should be noted that the previous suggestion of a tagatose 6P-kinase function for other members of this family has been debated.

D-tagatose-bisphosphate aldolase, class II, non-catalytic subunit; Aldolases specific for D-tagatose-bisphosphate occur in distinct pathways in Escherichia coli and other bacteria, one for the degradation of galactitol (formerly dulcitol) and one for degradation of N-acetyl-galactosamine and D-galactosamine. This family represents a protein of both systems that behaves as a non-catalytic subunit of D-tagatose-bisphosphate aldolase, required both for full activity and for good stability of the aldolase. Note that members of this protein family appear in public databases annotated as putative tagatose 6-phosphate kinases, possibly in error. [Energy metabolism, Sugars]

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
