alpha/beta hydrolases; A functionally diverse superfamily containing proteases, lipases, peroxidases, esterases, epoxide hydrolases and dehalogenases. The catalytic apparatus typically involves three residues (catalytic triad): a serine, a glutamate or aspartate and a histidine, and often the mechanism involves a nucleophilic attack on a carbonyl carbon atom.

Uncharacterized enzymes similar to novel bacterial esterase that cleaves esters on halogenated cyclic compounds; This family contains uncharacterized proteins similar to a novel bacterial esterase (Alcaligenes esterase 713) with the alpha/beta hydrolase fold but does not contain the GXSXXG pentapeptide around the active site serine residue as commonly seen in other enzymes of this class. Esterase 713 shows negligible sequence homology to other esterase and lipase enzymes. It is active as a dimer and cleaves esters on halogenated cyclic compounds though its natural substrate is unknown.

Novel bacterial esterase 713 that cleaves esters on halogenated cyclic compounds; This family contains proteins similar to a novel bacterial esterase (esterase 713) with the alpha/beta hydrolase fold that cleaves esters on halogenated cyclic compounds. This Alcaligenes esterase, however, does not contain the GXSXXG pentapeptide around the active site serine residue as seen in other esterase families. This enzyme is active as a dimer though its natural substrate is unknown. It has two distinct disulfide bridges; one formed between adjacent cysteines appears to facilitate the correct formation of the oxyanion cleft in the catalytic site. Esterase 713 also resembles human pancreatic lipase in its location of the acidic residue of the catalytic triad. It is possibly exported from the cytosol to the periplasmic space. A large majority of sequences in this family have yet to be characterized.

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
