Mode of Action (MoA)
|
binds to the Leptotrichia wadei Cas13-crRNA, inhibiting its activity.
|
|
Evidence
|
Ectopic expression (ECO_0000017) of AcrVIA3 protects against Cas13a-mediated interference in plaque and plasmid transformation assays. In vitro assays show AcrVIA3 inhibits Cas13a enzymatic activity (ECO_0000184). Co-immunoprecipitation indicates selective binding to the Cas13a-crRNA complex (ECO_0005644).
