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.
Several biological databases document protein superfamilies and protein folds, for example: Pfam - Protein families database of alignments and HMMs; PROSITE - Database of protein domains, families and functional sites; PIRSF - SuperFamily Classification System; PASS2 - Protein Alignment as Structural Superfamilies v2
The new Structural Classification of Proteins version 2 (SCOP2) database was released at the beginning of 2020. The new update featured an improved database schema, a new API and modernised web interface. This was the most significant update by the Cambridge group since SCOP 1.75 and builds on the advances in schema from the SCOP 2 prototype. [7]
The Mendeley research catalog is a crowdsourced database of research documents. Researchers have uploaded nearly 100M documents into the catalog with additional contributions coming directly from subject repositories like Pubmed Central and Arxiv.org or web crawls. Free Mendeley [98] Merck Index: Chemistry, biology, pharmacology: Also available ...
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 ...

The databases in the table below are selected from the databases listed in the Nucleic Acids Research (NAR) databases issues and database collection and the databases cross-referenced in the UniProtKB. Most of these databases are cross-referenced with UniProt / UniProtKB so that identifiers can be mapped to each other. [15] Proteins in human:
