Schematic representation of hBMP2nat, 27 kD γ-zein, and zein-hBMP2ad fusion. Dark gray box: human BMP2 active domain (ad); light gray box: 27 kD γ-zein N-terminal domain; hatched box: thrombin consensus cleavage site; black triangles: cysteine residues involved in interchain-disulfide bridges. N-glycosylated sites in hBMP2 are indicated. Intrachain disulphide bridges in hBMP2ad and in the C-terminal region of 27 kD γ-zein are indicated. SP: Signal Peptide. Expected Molecular Mass: hBMP2nat, 45.8 kD; hBMP2ad, 14 kD; 27 kD γzein, 23.7 kD; zein-hBMP2ad, 27.4 kD.
