Sysname
6-sulfo-alpha-D-quinovosyl diacylglycerol 6-sulfo-D-quinovohydrolase (configuration-retaining)
Reaction(IUBMB)
a 6-sulfo-alpha-D-quinovosyl diacylglycerol + H2O = 6-sulfo-alpha-D-quinovose + a 1,2-diacylglycerol [RN:
R11543 ]
Reaction(KEGG)
Substrate
6-sulfo-alpha-D-quinovosyl diacylglycerol;
H2O [CPD:
C00001 ]
Product
6-sulfo-alpha-D-quinovose [CPD:
C22077 ];
1,2-diacylglycerol [CPD:
C00641 ]
Comment
The enzyme, characterized from the bacteria Escherichia coli and Pseudomonas putida, hydrolyses terminal non-reducing alpha-sulfoquinovoside residues in alpha-sulfoquinovosyl diacylglycerides and alpha-sulfoquinovosyl glycerol using a retaining mechanism. The enzyme belongs to the glycosyl hydrolase GH31 family.
