Overview

Mode of Action (MoA) AlphaFold 3 predicts a direct interaction between Cas8a1 (https://www.ncbi.nlm.nih.gov/protein/WWV39459.1) and AcrIB9 (ipTM = 0.81, pTM = 0.8).
Evidence Ectopic expression of AcrIB5 (ECO_0000017) abolished interference against target plasmid. Binding it supported by computational structure modeling evidence (ECO_0006368).
