Figure 1. The Crystal Structure of the Hammerhead
Ribozyme(A) shows the three-dimensional crystal structure of the
hammerhead ribozyme in its initial state conformation. (B) is a
schematic diagram of this structure designed to complement (A).
The enzyme strand is shown in red, the substrate strand in
yellow, and the cleavage site base in green. Base pairing is
indicated by white lines (with broken lines indicating
noncanonical single H bond contacts), and pink lines indicate
base–ribose interactions.
