ASTRAL SCOP ASTEROIDS 1.67

Warning: This page contains sequence sets created using automated methods and no manual curation. For most users, we recommend the standard (manually curated) sequence sets.
Explanation: ASTEROIDS are predicted domains from PDB chains released since the last ASTRAL freeze date. They are updated weekly with newly released entries. Domains are predicted using BLAST sequence comparison with domains in the current ASTRAL release, hidden Markov models (HMMs) created from multiple sequence alignments of each family and superfamily in the current ASTRAL release, and HMMs from the Pfam-A database. Unassigned regions of at least 20 consecutive residues are also predicted to be potential domains. ASTEROIDS are available in a single file, as well as optionally available integrated into ASTRAL representative subsets selected according to two similarity criteria (BLAST E-value and % identity) at various thresholds.
More details are provided in the 1.65 release notes, the 1.67 release notes, and the 2004 NAR paper [PDF].

All ASTEROIDS sequences, based on SEQRES records reported by the PDB: asteroids-all-1.67-050906.fa

Percentage identity filtered subsets of combined ASTEROIDS and ASTRAL SCOP genetic domain sequences, based on PDB SEQRES records
with less than percent identity (using "in both" criterion).

E-value filtered subsets of combined ASTEROIDS and ASTRAL SCOP genetic domain sequences, based on PDB SEQRES records
with E-values >= (in a database size of 100,000,000 residues).
Browse (unaligned) FASTA files containing genetic domain sequences, based on PDB SEQRES records, for current ASTRAL families or superfamilies.
Browse the multiple alignment files of the latter sequences for current ASTRAL families or superfamilies.
Browse the hidden Markov models (HMMER format) for current ASTRAL families or superfamilies,
or download HMMER libraries containing HMMs for all families or superfamilies.
