Restriction of a Peptide Turn Conformation and Conformational Analysis of Guanidino Group Using Arginine-Proline Fused Amino Acids: Application to Mini Atrial Natriuretic Peptide on Binding to the Receptor
mini atrial natriuretic polypeptide, which has an important turnlike conformation at Gly(6)-Arg(7)()-Met(8)-Asp(9). Structural analysis revealed that the size of the conformational space of Arg(7) on binding to the receptor was approximately one-third of the entire conformational space.
