== Helix-Turn-Helix ==

This helix-loop-helix protein has one subunit. An <scene name='59/590622/9antcartoon/1'>alpha helix</scene> fits into a major groove in the DNA.

== Leucine Zipper ==

This leucine zipper protein has <scene name='59/590622/1ysaspacefillsubunits/1'>two subunits</scene>. An <scene name='59/590622/1ysacartoon/1'>alpha helix</scene> in each subunit fits into a major groove in the DNA. Interactions between <scene name='59/590622/1ysaleucines/1'>leucyl R groups</scene> help hold the subunits together.

== Zinc Finger ==

This zinc finger protein has one subunit. Three zinc finger motifs fit into a major groove in the DNA.
