Function

EALGL_SACD2 Catalyzes the depolymerization of alginate through an exolytic mode of action, via a beta-elimination mechanism. Preferentially acts on oligoalginates with degrees of polymerization higher than 2 to produce the alginate monomer, 4-deoxy-L-erythro-5-hexoseulose uronic acid.[1] [2]
