====== DNA-binding protein ======

DNA-[[binding protein]]s are proteins composed of DNA-binding domains and thus have a specific or general affinity for either single or double stranded DNA.

Sequence-specific DNA-binding proteins generally interact with the major groove of B-DNA, because it exposes more functional groups that identify a base pair. However, there are some known minor groove DNA-binding ligands such as netropsin,[distamycin, Hoechst 33258, [[pentamidine]], DAPI and others.
