Expression by plasmids containing
combinations of regulatory segments. FY23 cells were transformed
with various plasmids containing segments of the DAN1 promoter
fused to lacZ and grown under anaerobic or aerobic
conditions and analyzed as described in Materials and Methods. Cells
carried D1 or plasmids containing the fragments indicated fused
at –107, 5 bp upstream from the TATA site: D9, (–207
to –107); C6, (–570 to –525); C2, (–633
to –525); C5, (–570 to –525 plus –207
to –107); C1, (–633 to –525 plus –207
to –107).
