| Abstract |
The amino acids in 9 cyanogen bromide peptides have been placed in sequence starting from the NH2 terminus. The peptides account for residues 1 to 377 of the whole protein and include the largest (CNBr7, 119 residues) and the smallest (CNBr1, 2 residues) of the cyanogen bromide peptides. This region contains only 3 of the 20 lysine residues in the polypeptide chain. A high proportion of charged groups are present (28 of 66 arginine, 28 of 60 glutamic acid, and 24 of 65 aspartic acid residues). |
