Pfam is a database of protein families that includes their annotations and multiple sequence alignments generated using hidden Markov models. [ 1 ] [ 2 ] [ 3 ] The latest version of Pfam, 37.0, was released in June 2024 and contains 21,979 families. [ 4 ]
Stockholm format is a multiple sequence alignment format used by Pfam, Rfam and Dfam, to disseminate protein, RNA and DNA sequence alignments. [1] [2] [3] The alignment editors Ralee, [4] Belvu and Jalview support Stockholm format as do the probabilistic database search tools, Infernal and HMMER, and the phylogenetic analysis tool Xrate.
This is template for a protein family/domain as defined in biological databases such as Pfam. Template parameters [Edit template data] Parameter Description Type Status Symbol Symbol no description Line optional Name Name no description Line optional Image image fill in "NONE" if not needed to suppress the tracking category File optional Width width Width for image String optional Caption ...
HMMER is the core utility that protein family databases such as Pfam and InterPro are based upon. Some other bioinformatics tools such as UGENE also use HMMER. HMMER3 also makes extensive use of vector instructions to increase computational speed.
Fingerprints can encode protein folds and functionalities more flexibly and powerfully than can single motifs, their full diagnostic potency deriving from the mutual context afforded by motif neighbours. PROSITE PROSITE is a database of protein families and domains. It consists of biologically significant sites, patterns and profiles that help ...
Sequences and features retrieved from user-configurable and publicly registered servers, e.g. EMBL, EBI, PDB, Pfam, Rfam, UniProt Accession retrieval. Structure/model data retrieval from PDB and 3D-Beacons including PDBe, AlphaFold DB, SWISS-MODEL.
The Structural Classification of Proteins extended (SCOPe) database was released in 2012 with far greater automation of the same hierarchical system and is full backwards compatible with SCOP version 1.75. In 2014, manual curation was reintroduced into SCOPe to maintain accurate structure assignment.
TIGRFAMs is a database of protein families designed to support manual and automated genome annotation. [1] [2] [3] Each entry includes a multiple sequence alignment and hidden Markov model (HMM) built from the alignment. Sequences that score above the defined cutoffs of a given TIGRFAMs HMM are assigned to that protein family and may be ...
