Characteristic length of a sequence that a particular DNA binding motif can recognize

Value <=5 base pairs
Organism Bacteria Escherichia coli

Comments A DNA sequence should be 11 base pairs long to occur statistically only once in the E. Coli chromosome (Bion 102071). Two five base pair sequences fit into one 11 base pair sequence. Thus, according to above property, a protein dimer with one DNA binding motif per monomer can barely recognize a unique DNA sequence in E. Coli
