GC-rich DNA can also exist in a form known as Z-DNA, which forms a left-handed helix. … Glycine, proline, and hydroxyproline must be in their designated positions with the correct configuration. For example, hydroxyproline in the Y position increases the thermal stability of the triple helix, but not when it is located in the X position. The thermal stabilization is also hindered when the hydroxyl group has the wrong configuration.
