From Robert J. Spreitzer, University of Nebraska, July 2014

Phenotype: requires acetate, sensitive to light

Directed mutagenesis and chloroplast co-transformation of wild-type 2137 mt+ (CC-3269) were used to create an S379A substitution (TCA-GCA) in the Rubisco large subunit, which causes a decrease in Rubisco CO2/O2 specificity but not holoenzyme stability (Zhu and Spreitzer 1994). This is the original mutant strain. It was created due to previous studies of Synechococcus and Rhodospirillum rubrum Rubisco (Harpel and Hartman 1992; Lee and McFadden 1992). The strain has been maintained with acetate medium in darkness since its creation.
