Protein
Exo-oligoalginate lyase
Organism
Saccharophagus degradans (strain 2-40 / ATCC 43961 / DSM 17024)
Function
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.
Similarity
Belongs to the polysaccharide lyase 17 family.
