Figure S1. Estimation of the half-life
The half-life of the viability for BL21-AI(IY,1amb-immE3) was estimated in the absence of IY. A single fitted curve was generated using an exponential decrease model. The half-life was calculated from the equation for the fitted curve.
Figure S2. Estimation of the growth rates
The growth rates were estimated for BL21-AI(IY,1amb-immE3), the parent strain carrying pSH350, and for a vector control carrying pBR322 instead of pSH350. A single fitted curve was generated for each strain using an exponential increase model. The growth rates were calculated from the equations for the fitted curves.
