Class I fructose-1,6-bisphosphate (FBP) aldolases of the archaeal type (DhnA homologs); Class I fructose-1,6-bisphosphate (FBP) aldolases of the archaeal type (DhnA homologs) found in bacteria and archaea. Catalysis of the enzymes proceeds via a Schiff-base mechanism like other class I aldolases, although this subfamily is clearly divergent based on sequence similarity to other class I and class II (metal dependent) aldolase subfamilies.

predicted phospho-2-dehydro-3-deoxyheptonate aldolase; This model represents a clade of sequences related to fructose-bisphosphate aldolase (class I, included within pfam01791). The members of this clade appear to be phospho-2-dehydro-3-deoxyheptonate aldolases. This enzyme is the first step of the chorismate biosynthesis pathway. Evidence for this assignment is based on gene clustering and phylogenetic profiling. A group of species lack members of the three other types of phospho-2-dehydro-3-deoxyheptonate aldolase (represented by TIGR00034, TIGR01358 and TIGR01361), and also aparrently lack the well-known forms of step 2 (3-dehydroquinate synthase), but contain all other steps of the pathway: Desulfovibrio, Aquifex, Archaeoglobus, Halobacterium, Methanopyrus, Methanococcus and Methanobacterium. The clade of sequences represented here is limited strictly to this group of organisms. In Desulfovibrio, Aquifex, Archaeoglobus, Halobacterium and Methanosarcina the genes found by this model are clustered with other genes from the chorismate, phenylalanine, tyrosine and tryptophan biosynthesis pathways. In addition, these genes in Desulfovibrio, Archaeoglobus, Halobacterium, Methanosarcina and Methanopyrus are adjacent to a gene which hits pfam01959 which also has the property of having members only in those species which lack steps 1 and 2. Together these two genes appear to perform the synthesis of 3-dehydroquinate. It is presumed that the substrates and the chemical transformations involved are identical, but this has not yet been proven experimentally.

Class I aldolases; Class I aldolases. The class I aldolases use an active-site lysine which stabilizes a reaction intermediates via Schiff base formation, and have TIM beta/alpha barrel fold. The members of this family include 2-keto-3-deoxy-6-phosphogluconate (KDPG) and 2-keto-4-hydroxyglutarate (KHG) aldolases, transaldolase, dihydrodipicolinate synthase sub-family, Type I 3-dehydroquinate dehydratase, DeoC and DhnA proteins, and metal-independent fructose-1,6-bisphosphate aldolase. Although structurally similar, the class II aldolases use a different mechanism and are believed to have an independent evolutionary origin.

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,
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
