Motion in Hammerhead RNA [hammer]

[ jump to morphs ]

Classification Known RNA Motion [N-R-2]

1HMH Both Conformations

Comparison of all three RNA chains in the asymmetric unit reveals significant conformational changes. The largest difference is between chains A and E, which have an RMSD of about 2.8. This is caused primarily by the large rotation of the 5' end and the twisting of the helical region. There are a number of smaller-scale conformational changes associated with self-cleavage.
