| The inner surface of the superhelix exposes conserved residues of Cmr4 that we show are required for target-cleavage activity. |
| This USO repeat does not follow the rule of classical armadillo repeat proteins that form a right-handed superhelix. |
| Of course, this behavior can be attributed to deficiencies in the theory, but a more obvious explanation can be found in branching of the superhelix. |
| The double helix of DNA winds about individual nucleosomes, forming a superhelix. |
| Here we report the 3.0 Å crystal structure of unliganded Kapβ2, which consists of a superhelix of 20 HEAT repeats. |
| In fact, a wide range of structural proteins have coils in which two or three helices are wound around each other to form a left-handed superhelix conformation. |
