Mode of Action (MoA)
|
binds allosteric centre of the Cas9 protein inducing its dimerisation and reducing its DNA binding affinity
|
|
Evidence
|
Ectopic expression (ECO_0000017) of AcrIIA6 from a plasmid in Streptococcus thermophilus with a type II-A CRISPR-Cas system completely abolished immunity against the CRISPR-sensitive virulent phage D5842.
