Alginic Acid Degradation by Eliminases from Abalone Hepatopancreas

Journal of Biological Chemistry, 1967
Abstract Two separate alginic acid eliminases have been purified from abalone hepatopancreas. Alginase I appeared to be specific for β-1,4 bonds involving d-mannuronic acid units and apperently acts at random on internal bonds. Alginase II appeared to cleave 1,4 bonds involving l-guluronic acid and to work at or near chain ends.
