pyridoxal phosphate-dependent enzymes, D-cysteine desulfhydrase family; This model represents a family of pyridoxal phosphate-dependent enzymes closely related to (and often designated as putative examples of) 1-aminocyclopropane-1-carboxylate deaminase. It appears that members of this family include both D-cysteine desulfhydrase (EC 4.4.1.15) and 1-aminocyclopropane-1-carboxylate deaminase (EC 3.5.99.7).

Tryptophan synthase beta superfamily (fold type II); this family of pyridoxal phosphate (PLP)-dependent enzymes catalyzes beta-replacement and beta-elimination reactions. This CD corresponds to aminocyclopropane-1-carboxylate deaminase (ACCD), tryptophan synthase beta chain (Trp-synth_B), cystathionine beta-synthase (CBS), O-acetylserine sulfhydrylase (CS), serine dehydratase (Ser-dehyd), threonine dehydratase (Thr-dehyd), diaminopropionate ammonia lyase (DAL), and threonine synthase (Thr-synth). ACCD catalyzes the conversion of 1-aminocyclopropane-1-carboxylate to alpha-ketobutyrate and ammonia. Tryptophan synthase folds into a tetramer, where the beta chain is the catalytic PLP-binding subunit and catalyzes the formation of L-tryptophan from indole and L-serine. CBS is a tetrameric hemeprotein that catalyzes condensation of serine and homocysteine to cystathionine. CS is a homodimer that catalyzes the formation of L-cysteine from O-acetyl-L-serine. Ser-dehyd catalyzes the conversion of L- or D-serine to pyruvate and ammonia. Thr-dehyd is active as a homodimer and catalyzes the conversion of L-threonine to 2-oxobutanoate and ammonia. DAL is also a homodimer and catalyzes the alpha, beta-elimination reaction of both L- and D-alpha, beta-diaminopropionate to form pyruvate and ammonia. Thr-synth catalyzes the formation of threonine and inorganic phosphate from O-phosphohomoserine.

CBS_like: This subgroup includes Cystathionine beta-synthase (CBS) and Cysteine synthase. CBS is a unique heme-containing enzyme that catalyzes a pyridoxal 5'-phosphate (PLP)-dependent condensation of serine and homocysteine to give cystathionine. Deficiency of CBS leads to homocystinuria, an inherited disease of sulfur metabolism characterized by increased levels of the toxic metabolite homocysteine. Cysteine synthase on the other hand catalyzes the last step of cysteine biosynthesis. This subgroup also includes an O-Phosphoserine sulfhydrylase found in hyperthermophilic archaea which produces L-cysteine from sulfide and the more thermostable O-phospho-L-serine.

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
