-  "Class description: A twisted beta-sheet exposes four alpha-helices that are packed against one side of the sheet. Most important for DNA-binding is a KDWK motif at the N-terminus of the third alpha-helix. Residues of this alpha-helix and the KWDK motif contact bases through the major groove, but the alpha-helix does not insert into the major groove. The domain structure of some of the class members is supported by an overlaying zinc coordinating motif. (PMID 11427895, PMID 15649886)"
