A 13S globulin fraction of sesame protein that was homogeneous by ultracentrifugation, gel electrophoresis, and immunodiffusion was found to have molecular weight of 361,000 to 399,000 from sedimentation coefficient (S degree 20)w = 12,80), viscosity (*?* = 0.0325 dl/g), diffusion coefficient (D20,w = 3.46 x 10(-7)), and partial specific volume V = 0.718 ml/g). The integral numbers of amino acid residues per molecule calculated on the basis of 399,000 were as follows: Asp324, Thr149, Ser222, Glu580, Pro140, Gly301, Ala259, 1/2Cys59, Val233, Met57, Ile152, Tyr89, Phe132, His80, Lys64, Arg321, Trp35, and Amido-ammonia408. Valine and glycine were found as the only N-terminal amino acids present.
