Effect on GOX reporter activity of point mutations in the four CreA consensus target sites (indicated in the schematic). GOX activities (averages and standard deviations) in sVAL040 (argB2/argB+ metG1 biA1 xlnBp::goxC), sVAL040-mC1/C2 (argB2/argB+ metG1 biA1 xlnBmC1/C2::goxC), sVAL040-mC3/C4 (argB2/argB+ metG1 biA1 xlnBmC3/C4::goxC), and sVAL040-mC1/C2/C3/C4 (argB2/argB+ metG1 biA1 xlnBmC1/C2/C3/C4::goxC) are shown relative to that of the sVAL040 strain in xylose. Extracts of the indicated strains were obtained 6 h after transfer to inducing (X) and inducing/repressing (XG) conditions.
