Cytokinin dehydrogenase 1, FAD and cytokinin binding; Members of this family adopt an alpha+beta sandwich structure with an antiparallel beta-sheet, in a ferredoxin-like fold. They are predominantly found in plant cytokinin dehydrogenase 1, where they are capable of binding both FAD and cytokinin substrates. The substrate displays a 'plug-into-socket' binding mode that seals the catalytic site and precisely positions the carbon atom undergoing oxidation in close contact with the reactive locus of the flavin.

sugar 1,4-lactone oxidases; This model represents a family of at least two different sugar 1,4 lactone oxidases, both involved in synthesizing ascorbic acid or a derivative. These include L-gulonolactone oxidase (EC 1.1.3.8) from rat and D-arabinono-1,4-lactone oxidase (EC 1.1.3.37) from Saccharomyces cerevisiae. Members are proposed to have the cofactor FAD covalently bound at a site specified by Prosite motif PS00862; OX2_COVAL_FAD; 1.

FAD binding domain; This family consists of various enzymes that use FAD as a co-factor, most of the enzymes are similar to oxygen oxidoreductase. One of the enzymes Vanillyl-alcohol oxidase (VAO) has a solved structure, the alignment includes the FAD binding site, called the PP-loop, between residues 99-110. The FAD molecule is covalently bound in the known structure, however the residue that links to the FAD is not in the alignment. VAO catalyzes the oxidation of a wide variety of substrates, ranging form aromatic amines to 4-alkylphenols. Other members of this family include D-lactate dehydrogenase, this enzyme catalyzes the conversion of D-lactate to pyruvate using FAD as a co-factor; mitomycin radical oxidase, this enzyme oxidizes the reduced form of mitomycins and is involved in mitomycin resistance. This family includes MurB an UDP-N-acetylenolpyruvoylglucosamine reductase enzyme EC:1.1.1.158. This enzyme is involved in the biosynthesis of peptidoglycan.

galactonolactone dehydrogenase; This model represents L-Galactono-gamma-lactone dehydrogenase (EC 1.3.2.3). This enzyme catalyzes the final step in ascorbic acid biosynthesis in higher plants. This protein is homologous to ascorbic acid biosynthesis enzymes of other species: L-gulono-gamma-lactone oxidase in rat and L-galactono-gamma-lactone oxidase in yeast. All three covalently bind the cofactor FAD.

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.

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) 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
