| Accepted name: |
sulfoquinovosidase |
| Reaction: |
a 6-sulfo-α-D-quinovosyl diacylglycerol + H2O = 6-sulfo-α-D-quinovose + a 1,2-diacylglycerol |
| Glossary: |
quinovose = 6-deoxy-D-glucopyranose |
| Other name(s): |
yihQ (gene name); 6-sulfo-α-D-quinovosyl diacylglycerol 6-sulfo-D-quinovohydrolase |
| Systematic name: |
6-sulfo-α-D-quinovosyl diacylglycerol 6-sulfo-D-quinovohydrolase (configuration-retaining) |
| Comments: |
The enzyme, characterized from the bacteria Escherichia coli and Pseudomonas putida, hydrolyses terminal non-reducing α-sulfoquinovoside residues in α-sulfoquinovosyl diacylglycerides and α-sulfoquinovosyl glycerol using a retaining mechanism. The enzyme belongs to the glycosyl hydrolase GH31 family. |
