TABLE 1:

Activation of the UPR in wild-type and mutant strains.

Strain β-Galactosidase units
Wild type 1.5 ± 0.009
emp24Δ 6.3 ± 0.005
bst1Δ 10 ± 0.021
bst1Δ emp24Δ 15.4 ± 0.021

β-Galactosidase assays were performed on strains harboring the reporter construct (pJC31). Activity is given in β-galactosidase units and represents the average of four independent determinations with SE.
