ENZYME entry: EC 3.2.1.159

PURL: https://purl.expasy.org/enzyme/EC/3.2.1.159
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
Comment(s)
  • 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 3.2.1.81 and EC 3.2.1.159 can be used to degrade agarose to 3,6-anhydro-L-galactose and D-galactose.
