The PurP guanine co-repressor binding site includes stacking interactions as well as hydrogen bonded ones. | The <scene name='55/554904/Cv/2'>PurP guanine co-repressor binding site includes stacking interactions as well as hydrogen bonded ones</scene>. Water molecules shown as red spheres. The DNA binding domain contains a helix-turn-helix-loop-helix motif which interacts with the DNA major groove and a hinge helix binding to to the DNA minor groove. Residue L53 interdigitates with the DNA central base pair<ref>PMID:9278422</ref>. | ||
