The B3 DNA binding domain (DBD) is a highly conserved domain found exclusively in transcription factors from higher plants (≥40 species) (Pfam PF02362) combined with other domains (IPR003340). It consists of 100-120 residues includes seven beta strands and two alpha helices that form a DNA-binding pseudobarrel protein fold (SCOP 117343); it interacts with the major groove of DNA.
