TBP causes the minor groove to be widened to an almost flat conformation; it also bends the DNA by an angle of 80. The interaction between TBP and DNA involves only a limited number of hydrogen bonds between the protein and the edges of the base pairs in the minor groove.  Instead, much of the specificity is imposed by two pairs of phenylalanine side chains that intercalate between the base pairs at either end of the recognition sequence and drive the strong bend in the DNA.

PTI and fungal pathogen entry into epidermal tissue induces several specific cytochrome P450 enzymes, and this leads to accumulation of the indole glucosinolate 4‐methoxyindol‐3‐ylmethylglucosinolate (4M13G).
