The structure of the 7 S globulin from Phaseolus vulgaris , phaseolin, was determined by small angle X‐ray scattering. The molecule consists of 3 Y‐shaped subunits which are arranged around a 3‐fold symmetry axis. Though phaseolin is structurally very similar to canavalin, the 7 S globulin from Canavalia ensiformis , there are considerable differences between the structure of crystalline canavalin and that of phaseolin in solution. The differences may be caused by tryptic treatment of canavalin before crystallization.
