TBP Binds to and Distorts DNA Using a b Sheet Inserted into the Minor Groove

TBP uses an extensive region of  sheet to recognize the minor groove of the TATA element . This is unusual. More typically, proteins recognize DNA using  helices inserted into the major groove of DNA, as we have seen and also for the factor .
