Experimentally Studied Proteins2

FASTA asparaginasedb_esp.fasta · 99 sequences · 35 kB

Sequences of the experimentally studied proteins, headed by UniProt accession and classification code. Also available as a BLAST target database.

Swiss-Prot Sequences2

FASTA asparaginasedb_sp.fasta · 127 sequences · 50 kB

Sequences of every Swiss‑Prot entry in the database, headed by UniProt accession and classification code. Also available as a BLAST target database.

Download FASTA

Some of the experimentally studied proteins are not present in asparaginasedb_esp.fasta: their sequences are reported only in the source publication and have no UniProt entry. Every other entry is included, and each sequence header gives the UniProt accession — use it to retrieve the full record from UniProt.
