Abstract:
The structural compositions of the most active deoxyribozyme and its derivatives have been examined by electrophoresis, and their crystallization conditions were surveyed for X-ray analysis. It has been found that Mg2+ ion is essential to form the active binary complex between the catalytic DNA and the substrate, and that heat-treatment is effective to prevent formation of the inactive quaternary complex between the two enzymes and the two substrates. Crystals obtained by the hanging drop vapor diffusion method are composed of the active binary complex.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
