Figure 2.
Residue 148 of RseA plays an important role for Site-2 cleavage. (A) Mutation of Val-148 to Thr or Ile, but not His or Lys, allowed Site-2 cleavage. DegS and OMP peptide were added together to the reactions where DegS is indicated. (B) Mutation of Val-148 to Thr or Ile in RseA allowed a more robust envelope stress response than mutation of Val-148 to His or Lys.
