ENZYME entry: EC 3.2.1.81

PURL: https://purl.expasy.org/enzyme/EC/3.2.1.81
Accepted Name
beta-agarase
Alternative Name(s)
agarase
endo-beta-agarase
Reaction catalysed
Hydrolysis of (1->4)-beta-D-galactosidic linkages in agarose, giving the tetramer as the predominant product
Comment(s)
  • 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.
