Directed mutagenesis and nuclear-gene transformation of rbcS∆-T60-3 mt- (CC-4415) were used to change the codon for Phe-132 (TTC) in the Rubisco small subunit to an ocher nonsense codon (TAA), which causes the deletion of nine carboxyl-terminal residues. The mutant Rubisco has decreases in carboxylation catalytic efficiency and thermal stability. This strain has been maintained with acetate medium in darkness to prevent selection for secondary mutations that may improve Rubisco function or stability.
