Complex between α-Chymotrypsin and poly(ethylene glycol) catalytically active in organic media

Abstract

α-Chymotrypsin and poly(ethylene glycol) were mixed in an aqueous phosphate buffer solution and lyophilized. The preparation was readily soluble in anhydrous isooctane. The polymer/enzyme complex, i.e., poly(ethylene glycol)/α-chymotrypsin, was catalytically active in anhydrous isooctane even when the molecular ratio of them was unity.
