Dimers arginine-aspartic acid

Fig. 4. Schematic representation (not to scale) of the amino acid sequence of fibronectin. Fibronectin is a dimer of two identical subunits (60 to 70 nm long and 2 to 3 nm long) covalently linked by a pair of disulfide bonds. The arginine-glycine-aspartic acid adhesive peptide ( ) starts at peptide sequence 1615. (The schematic was redrawn using information obtained from the following references Ayad et al., 1994 Mathews and van Holde, 1990 and Darnell et al, 1990.)...
