Abstract
Adhesive proteins isolated from mature plants selected from the group consisting of macroalgae and microalgae, said proteins being characterized by the presence of at least one RGD or RGD-like or other adhesive recognition sequence, the absence of DOPA and hydroxyproline units, and by the fact that the proteins may be used by the plants in their natural state, for the purpose of adhesion to substrates.
Claims20
Adhesive proteins which possess the following characteristics:
- (a) said adhesive proteins have been isolated from the holdfast of mature macroalgae;
- (b) said adhesive proteins do not contain hydroxyproline units;
- (c) said adhesive proteins do not contain 3,4-dihydroxyphenyl-L-alanine (DOPA) units;
- (d) said adhesive proteins interfere with the binding of T-cells to an extracellular matrix;
- (e) said adhesive proteins are insoluble in water when water is use as an extraction medium extract proteins from said holdfast of mature macroalgae;
- and
- (f) said adhesive proteins may be used by said mature macroalgae, in the natural state of said mature macroalgae, to adhere to a substrate.
