Enzyme Information

3.2.1.81
Beta-agarase.
based on mapping to UniProt D7GXG4
Hydrolysis of (1->4)-beta-D-galactosidic linkages in agarose, giving the tetramer as the predominant product.
-!- Also acts on porphyran, but more slowly. -!- Cleaves the beta-(1->4) linkages of agarose in a random manner with retention of the anomeric-bond configuration, producing beta-anomers that give rise progressively to alpha-anomers when mutarotation takes place. -!- The end products of hydrolysis are neoagarotetraose and neoagarohexaose in the case of AgaA from the marine bacterium Zobellia galactanivorans, and neoagarotetraose and neoagarobiose in the case of AgaB.
