Selected binding sites for each Mnt variant obtained in the SELEX experiments. The binding sites, which contain the conserved core operator sequence CCACSGTGG (shaded), are aligned between the spaces in the sequences. Upper case letters are from the randomized regions and lower case letters are from the fixed regions. Sometimes a fixed region obtained a mutation, and those have been capitalized (e.g. H6A:1). The number in parentheses following some of the sequences are the number of times that sequence appeared in the selected collection.
