γ-Protein, a sulphur amino acid rich protein from pigeon pea (Cajanus cajan (L.) Millsp.)

Abstract

A globulin protein comparatively rich in sulphur amino acids has been isolated from the seeds of pigeon pea. This protein termed γ-protein has a sedimentation coefficients of 7S and a molecular weight of about 90,000. Antibodies were raised against pure γ-protein. Using rocket immunoelectrophoresis it was observed that γ-protein was synthesised in the developing seeds, 21 days after flowering.
