In addition, they are resistant to hydrolysis by exo- and endo-nucleases. They have become noticeable as antisense DNA analogs in recent years.展开更多

The effects of hydrophobitities, α-helix-forming tendencies, and basicities of peptides on their affinities for calmodulin were studied. Model peptides were designed to examine the calmodulin-binding domain model and the prediction method. The determined dissociation constants of the complexes formed from the model peptides and calmodulin are in good agreement with the predicted results.展开更多
