Plasmid pNESS2-C65S was used to transform rbcL-L290F/rbcS∆-CAL005.01.13 mt+ (Genkov et al. 2006). This strain is like revertant R88-5A (Genkov et al. 2006), but it lacks the wild-type rbcS1 gene. The small-subunit C65S substitution increases the CO2/O2 specificity of the original large-subunit L290F mutant enzyme (Du et al. 2000; Genkov et al. 2006). This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.
