FIG. 1

Electrophoretic mobility shift analysis of binding of SspA to the sspB upstream promoter-containing region. A 364-bp 32P-labeled sspB upstream fragment was used as the probe. Reaction mixtures contained probe alone (lane 1), probe with SspA protein (lane 2), probe with SspA and excess unlabeled probe (lane 3), probe with SspA protein and excess E. coli DNA (lane 4), or probe with sonicated E. coli extract containing cloned DNA binding domain from EBNA-1 (lane 5).
