EC 3.2.1.159 Alpha-neoagaro-oligosaccharide hydrolase. [-]    

Reaction: 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.
Other name(s): Alpha-Naos hydrolase. Alpha-neoagarooligosaccharide hydrolase.
Comments: 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.
