ResumoA set of arc operators with transition and/or transversion mutations at each operator base pair has been constructed. By determining the ability of Arc to bind these variant operators, the importance of each base pair for Arc recognition has been assessed. Methylation protection experiments have also been used to probe points of close contact between Arc and most of the mutant operators. These data, together with phosphate interference results obtained previously for the wild type operator, provide information about the operator surface that is contacted when Arc binds.
