Download data from anti-CRISPRdb
The core dataset
Anti-CRISPR ID, protein accession number,
activity, protein source, protein sequence,
comment, and coding region for each anti-CRISPR
protein can be obtained.
Nucleotide sequences (from NCBI)
Nucleic acid sequences were extracted from NCBI
according to their coding regions. Some anti-CRISPRs
have no coding region annotation. Therefore,
there are fewer nucleic acid sequences than
protein sequences in the database.
Structures and interactors
All the available structures from the PDB database
and interactors from the STRING and the DIP databases for
each anti-CRISPR protein are provided in this dataset.

Inhibitory strength
One Acr may have different inhibitory strength for different Cas proteins, such as AcrIF1 is potent inhibitory for I-F system in P.aeruginosa, whereas it has weak blocking function for I-F system in P.atrosepticum.
We therefore collect such data. Download inhibitory strength here.
Please note that the data is being updated.
