Abstract

A method is described for isolating conarachin II in a homogeneous form by the techniques of DEAE-cellulose chromatography, polyacrylamide gel electrophoresis and sedimentation velocity. The protein contains 0.72% carbohydrate and no phosphate. Hydrogen ion titration curve indicated that the sidechain carboxyl, imidazole and €-amino groups titrated with normal pKInt values and their number agreed with the analytical values obtained from amino acid analysis. However, tyrosine phenolic groups had abnormal pKint of 10.5.
