Factors Influencing the Size of PEO Complexes with a Tyrosine-Rich Polypeptide
Abstract
Aqueous complexes of PEY1, a 36 100 Da random synthetic peptide of tyrosine (50 mol %) and glutamic acid (50 mol %), with poly(ethylene oxide) (PEO) were studied as functions of PEO molecular weight, mixing ratio of PEO and PEY1, and the presence of calcium ions. Without calcium ions, the complexes were water soluble, with each complex consisting of a single PEO chain with many bound PEY1 chains. In the presence of 1 mM calcium ions, PEY1 …
