CC-4640 PAADA/76-5EN(11-4) mt-

Phenotype: requires acetate, sensitive to light

This is progeny 4 from tetrad 11 from a cross between PAADA mt+ and 76-5EN mt- (Hong 1996). The strain can grow on acetate medium with 50 µg/mL spectinomycin in darkness, but dies with 250 µg/mL spectinomycin, indicating that 76-5EN partially blocks expression of aadA from the engineered rbcL promoter (Hong 1996). This strain requires acetate for growth because 76-5EN also blocks expression of the native rbcL gene (Hong and Spreitzer 1994). It has been maintained with acetate medium in darkness since it was isolated.
