From Robert J. Spreitzer, University of Nebraska, November 2014
Using standard methods of directed mutagenesis and chloroplast transformation of rbcL∆-MX3312 mt+ (CC-4696) (Satagopan and Spreitzer 2004), Boon Hoe Lim in Spreitzer’s group created two substitutions (V221C and I265V) together in the Rubisco large subunit. This mutant was created to investigate the molecular basis for the increased CO2/O2 specificity of mutant rbcL-Penta/rbcS1-ABSO mt+ (CC-4848) (Spreitzer et al. 2005). This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function.
