The results show that the selectivity of (S)-CPW399 toward full-length GluR2 relative to GLUR3 is reflected in the binding data on the two soluble constructs, allowing the use of (Y702F)GluR 2-S1S2J as a model system for studying Glu R2/Glu R3 selectivity.

The structural diversity of this PNA demonstrates how the PNA backbone is able to adapt to structures governed by the stacking and hydrogen-bonding interactions between the nucleobases.

The crystal structure of the carbohydrate recognition domain (CRD) of human TN (TN3) has been determined separately at 2.0 A resolution in order to obtain detailed information on the two calcium binding sites, essential for the elucidation of the specificity of TN towards oligosaccharides.

Compound bT is shown to be an effective mimic of the natural thymine nucleobase in Pna-DNA, PNA-RNA, and PNA -PNA duplex structures and tricyclic derivative tC in place of cytosine in PNA oligomers increased the thermal stability and the sequence specificity was diminished in some PNA's duplex systems.
