Inclusion bodies membrane
WebUncontrolled basal expression can affect host cell growth and decrease protein yield, while overly robust induction can result in inclusion bodies. Exporting a protein to the E. coli periplasm or the inner membrane introduces more complications for targets that must be folded with disulfide bonds or incorporated into a membrane.
