The high-resolution solution structure of a monomeric circular permuted (cp) variant of the potent HIV-inactivating protein cyanovirin-N (CV-N) was determined by NMR. Comparison with the wild-type (wt) structure revealed that the observed loss in stability of cpCV-N compared to the wt protein is due to less favorable packing of several residues at the pseudo twofold axis that are responsible for holding the two halves of the molecule together ...
