A fragment containing two identical 5′-CATTTGGC-3′ repeats and a third, similar repeat is essential for responsiveness of the STL1 to osmotic pressure. Top, deletions performed in the context of the full-length STL1 promoter (704 base pairs); bottom, the β-galactosidase activities of the resulting promoters. Note that the 5′ deletion constructs –636STL1-LacZ and –626STL1-LacZ, one of which contains the third repeat and the other does not, were included in the experiment.
