The characterization of the 12 S "globulin" from rapeseed and its glycoprotein component

A 12 S globulin was isolated from each of the two species of rapeseed (B. napus L. and B. campestris L.) and they have been shown to be similar in terms of amino acid composition, amino terminal amino acids, number of subfractions, and carbohydrate content. One of the major proteins, a glycoprotein, present in each of the 12 S aggregates, was isolated and purified. Its amino acid composition, carbohydrate content, N-terminal amino acids, and sedimentation coefficient are reported herein.
