Percentage absolute deviation from optimal protein expression per carbon source. Only four carbon sources show a percentage deviation of more than 10%: ornithine (10.2%), glycerol (12.7%), alanine (12.3%) and asparagine (30.3%). Mean absolute deviation is 6.1 ± 6.1% and with those four carbon sources removed 4.3 ± 3.0%. The growth rates of the wildtype and the mutant were compared at the optimal IPTG concentration.
