Serine dehydratase alpha chain; L-serine dehydratase (EC:4.2.1.13) is a found as a heterodimer of alpha and beta chain or as a fusion of the two chains in a single protein. This enzyme catalyzes the deamination of serine to form pyruvate. This enzyme is part of the gluconeogenesis pathway.

L-serine dehydratase, iron-sulfur-dependent, single chain form; This enzyme is also called serine deaminase and L-serine dehydratase 1. L-serine ammonia-lyase converts serine into pyruvate in the gluconeogenesis pathway from serine. This enzyme is comprised of a single chain in Escherichia coli, Mycobacterium tuberculosis, and several other species, but has separate alpha and beta chains in Bacillus subtilis and related species. The beta and alpha chains are homologous to the N-terminal and C-terminal regions, respectively, but are rather deeply branched in a UPGMA tree. This enzyme requires iron and dithiothreitol for activation in vitro, and is a predicted 4Fe-4S protein. Escherichia coli Pseudomonas aeruginosa have two copies of this protein.

L-serine dehydratase, iron-sulfur-dependent, alpha subunit; This enzyme is also called serine deaminase. L-serine dehydratase converts serine into pyruvate in the gluconeogenesis pathway from serine. This model describes the alpha chain of an iron-sulfur-dependent L-serine dehydratase, found in Bacillus subtilis. A fairly deep split in a UPGMA tree separates members of this family of alpha chains from the homologous region of single chain forms such as found in Escherichia coli. This family of enzymes is not homologous to the pyridoxal phosphate-dependent threonine deaminases and eukaryotic serine deaminases.

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,

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)
