Yield and efficiency were computed by searching the 2-D parameter space consisting of the transcription rate constant for σ32 and the association constant between σ32 and DnaK as follows:
for the various systems,(A) DEG-FB/FF double mutant (SEQ-FB system): K[5] = K[6] = 0 M−1, kx[1] = kx[2] = 0 min−1, η = 1,
(B) FF mutant (SEQ-FB + DEG-FB system): K[5] = K[6] = 1 × 108 M−1, kx[1] = kx[2] = 5 min−1, η = 1,
(C) Wild-type (SEQ-FB +DEG-FB + FF system): K[5] = K[6] = 1 × 108 M−1, kx[1] = kx[2] = 5 min−1, η = 1 (low), η = 2 (high).
