Overview

Mode of Action (MoA) Expression of Stp alleviates the restriction, and it is proposed that it binds to EcoPrrI. It triggers PrrC defence, and both inhibition and activation depend on the same residues within the N-proximal 18-residue region of Stp.
Evidence Ectopic expression evidence supports anti-RM activity (ECO_0000017)
