Comparison of the structure of the 7 S globulin from Phaseolus vulgaris in solution with the crystal structure of 7 S globulin from Canavalia ensiformis by small angle X-ray scattering

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 Canav...

Description
Summary: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.
