Abstract

The conformation of three sequential copolypeptides, poly(L‐tyrosyl‐L‐lysine), poly(L‐tyrosyl‐L‐lysyl‐L‐lysine), and poly[L‐tyrosyl‐(L‐lysyl)~2~‐L‐lysine] have been studied by a variety of techniques, including CD, ir spectroscopy, analytical ultracentrifugation, and x‐ray diffraction. Depending upon the pH and sovent composition, poly(L‐tyrosyl‐Llysyl‐L‐lysine) and poly [L‐tyrosyl‐(Llysyl)~2~‐L‐lysine] can adopt either the α‐helical or random‐coil conformation, while poly(L‐tyrosyl‐L‐lysine) forms either inter‐ or intramolecular β‐structures.
