ENZYME entry: EC

Accepted Name
Alpha-neoagaro-oligosaccharide hydrolase.
Alternative Name(s)
Alpha-NAOS hydrolase.
Alpha-neoagarooligosaccharide hydrolase.
Reaction catalysed
Hydrolysis of the 1,3-alpha-L-galactosidic linkages of neoagaro-oligosaccharides that are smaller than a hexamer, yielding 3,6-anhydro-L-galactose and D-galactose
  • When neoagarohexaose is used as a substrate, the oligosaccharide is cleaved at the non-reducing end to produce 3,6-anhydro-L-galactose and agaropentaose, which is further hydrolyzed to agarobiose and agarotriose.
  • With neoagarotetraose as substrate, the products are predominantly agarotriose and 3,6-anhydro-L-galactose.
  • In Vibrio sp. the actions of EC and EC can be used to degrade agarose to 3,6-anhydro-L-galactose and D-galactose.
