SUPERFAMILY HMM library and genome assignments server

SUPERFAMILY Description

SUPERFAMILY is a database of structural and functional protein annotations for all completely sequenced organisms.

A domain is the smallest unit of evolution; a large protein can be split into smaller domains. Domains can occur by themselves or in combination with other domains. A superfamily groups together domains of different families which have a common evolutionary ancestor based on structural, functional and evolutionary data.
The SUPERFAMILY web site and database provides protein domain assignments, at the SCOP 'superfamily' and 'family' levels, for the predicted protein sequences in over 900 organisms, (plus sequence collections such as UniProt). Please contact us if you think we have missed any organisms.
SUPERFAMILY domain assignments are generated using an expert curated set of profile hidden Markov models. All models and structural assignments are available for browsing and download. Sophisticated tools are provided for the analysis of superfamily (and family) domain assignments.

Major Features

Sequence search

Submit your protein, or DNA, sequence for superfamily and family level classification.

Keyword search

Search for superfamily names, family names, species names, sequence IDs, SCOP IDs, PDB IDs and hidden Markov model IDs.

Domain assignments

Domain assignments, alignments and architectures for completely sequenced eukaryotic, and prokaryotic organisms. Additional sequence collections are also included.

Comparative genomics tools

Browse unusual (over- and under-represented) superfamilies and families, adjacent domain pair lists and graphs, unique domain pairs, domain combinations, domain architecture co-occurrence networks and domain distribution across taxonomic kingdoms for each organism.

Genome statistics

For each genome: number of sequences, number of sequences with assignment, percentage of sequences with assignment, percentage total sequence coverage, number of domains assigned, number of superfamilies assigned, number of families assigned, average superfamily size, percentage produced by duplication, average sequence length, average length matched and number of domain pairs.

Superfamily annotation InterPro have added abstracts for 1,052 superfamilies, and 763 superfamilies have some gene ontology annotation.
Functional annotation

Functional annotation of SCOP 1.69 superfamilies. By Christine Vogel.

Profile comparison

For finding remote domain matches. Available when the sequence search fails to find a significant match. Profile comparison (PRC) for aligning and scoring two profile hidden Markov models by Martin Madera.

Hidden Markov models

Produce SCOP domain assignments for your sequences using the SUPERFAMILY models. HMM visualisation by Martin Madera, e.g. model 0045110.
