(A) DNase I footprint of protection by SspA of a 279-bp sspB upstream region. Lane 1, Maxam and Gilbert A+G ladder; lanes 2 to 5, DNase I treatment in the presence of 0, 1, 2, and 4 μg of SspA, respectively. The 32-bp protected sequence is indicated by a bracket. (B) DNA sequence upstream of sspB. The 32-bp region protected from DNase I digestion is underlined.
