Isolation from the marine mollusk Lambis sp and catalytic properties of an alginate lyase with rare substrate specificity

Homogeneous alginate lyase with rare specificity exhibiting maximum activity at pH 5.0 and temperature range 40-55A degrees C that catalyzed cleavage of 1 -> 4 glycoside bonds between alpha-L-guluronic acid residues was isolated from liver-pancreas of the marine gastropod mollusk Lambis sp. The alginate lyase was classified as a poly-1 -> 4-alpha-L-guluronate lyase (EC 4.2.2.11).
