ID 3.2.1.81 DE beta-agarase. AN agarase. AN endo-beta-agarase. CA Hydrolysis of (1->4)-beta-D-galactosidic linkages in agarose, giving the CA tetramer as the predominant product. CC -!- Also acts on porphyran, but more slowly. CC -!- Cleaves the beta-(1->4) linkages of agarose in a random manner with CC retention of the anomeric-bond configuration, producing beta-anomers CC that give rise progressively to alpha-anomers when mutarotation takes CC place. CC -!- The end products of hydrolysis are neoagarotetraose and CC neoagarohexaose in the case of AgaA from the marine bacterium CC Zobellia galactanivorans, and neoagarotetraose and neoagarobiose in CC the case of AgaB.
