[Catalytic properties of endo-1,3-beta-D-glucanase from the Vietnamese edible mussel Perna viridis].

A beta-1,3-glucanase with a molecular mass of 33 kDa was isolated in the homogeneous state from a crystalline stalk of the commercially available Vietnamese edible mussel Perna viridis. It hydrolyzes beta-1,3-bonds in glucans and is capable of catalyzing the transglycosylation reaction. The beta-1,3-glucanase has a K(m) value of 0.
