Some characteristics of the alkali-soluble protein from the red alga Furcellaria fastigiata

From the red agar-bearing alga furcellaria we have isolated an alkali-soluble protein. Its aminoacid composition and N-terminal acid — arginine — have been determined. It has been shown to belong to the group of glycoproteins. One of the possible types of carbohydrate — protein bonds is a O-glycosidic bond.
