Abstract: | To further define the molecular interaction between decorin and type I collagen we generated a 20 kD fragment containing the N-terminal half of the core protein by Endoproteinase Arg C digestion and a 40 kD fragment including all leucine-rich repeats in the central part of decorin core by cleavage with 2-nitro-5-thiocyanobenzoate. The fragments did not influence collagen fibril formation, even at high concentration, and radioactive fragments showed little binding to collagen fibrils. Our observations suggest that neither the N-terminal half nor the central leucine-rich repeats of the decorin core protein can, by itself, interact fully with fibrillar collagen. |
