Enzymatic footprinting
WebJan 1, 2004 · In theory this should provide a more accurate assessment of the binding footprint than chemical and enzymatic footprinting methods where access of the reagent/enzyme may be restricted to regions blocked by but not directly bound to the protein. In addition, sequence and/or nucleotide specificity associated with chemical … WebDNA footprinting is a term that defines a collection of methods to analyze protein–DNA complexes and to identify the position of the binding site. When a protein binds to a specific site on a DNA sequence, footprinting helps to identify where the binding site is. In addition, it can also give some clues on the specificity of the binding and ...
