| Accepted name: |
funoran endo-α-hydrolase |
| Reaction: |
Endohydrolysis of α-(1→3)-linkages between 3,6-anhydro-α-L-galactopyranose and β-D-galactopyranose-6-sulfate units in funoran |
| Glossary: |
funoran = [→4)-3,6-anhydro-α-L-galactopyranose-(1→3)-β-D-galactopyranose-6-sulfate-(1→] |
| Other name(s): |
α-funoranase |
| Systematic name: |
funoran endo α-(1,3)-glycanohydrolase |
| Comments: |
The enzyme is an endo hydrolase that hydrolyses the α-(1→3) bond in funoran, a polysaccharide produced by red algae of the genus Gloiopeltis. The cleavage point is different from funoran endo-β-hydrolase (EC 3.2.1.222). The enzyme from the marine bacterium Aquimarina sp. AD1 also cleaves the α-(1→3) glycosidic bond between 3,6-anhydro-α-L-galactopyranose and β-D-galactopyranose of agarose (cf. EC 3.2.1.158, α-agarase). The anomeric configuration of the product (configuration retaining or inverting) has not yet been determined. |
