Accepted name: |
galactose-6-sulfurylase |
Reaction: |
Eliminates sulfate from the D-galactose 6-sulfate residues of porphyran, producing 3,6-anhydrogalactose residues |
Glossary: |
porphyran = is a linear polysaccharide produced by the red algae Porphyra. Its backbone is composed of about 30% agarose repeating units (alternating D-galactose and 3,6-anhydro-α-L-galactopyranose residues joined by α-(1→3)- and β-(1→4)-linkages), with the remaining residues being 3-linked β-D-galactopyranose and 4-linked α-L-galactopyranose-6-sulfate. |
Other name(s): |
porphyran sulfatase; galactose-6-sulfatase; galactose 6-sulfatase |
Systematic name: |
D-galactose-6-sulfate:alkyltransferase (cyclizing) |
