Abstract: | Theoretical conformational analysis was used to study the spatial structure of a putative binding site responsible for binding of p21 oncoproteins to other oncoproteins. Conformational properties of the isolated address sequence localized in fragment 34-46 of native p21 and of the decapeptide molecule corresponding to the 35-44 sequence in the primary structure of oncoproteins of this family were revealed. Our calculations demonstrated a similarity between the spatial structures of the peptides, which confirms the hypothesis on the identity of their biological functions. |
