Jump to: navigation, search

In enzymology, a triglucosylalkylacylglycerol sulfotransferase (EC is an enzyme that catalyzes the chemical reaction

3'-phosphoadenylyl sulfate + alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,3-1-O- alkyl-2-O-acylglycerol adenosine 3',5'-bisphosphate + 6-sulfo-alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,6-alpha-D-glucosyl- 1,3-1-O-alkyl-2-O-acylglycerol

The 3 substrates of this enzyme are 3'-phosphoadenylyl sulfate, alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,3-1-O-, and alkyl-2-O-acylglycerol, whereas its 3 products are adenosine 3',5'-bisphosphate, 6-sulfo-alpha-D-glucosyl-1,6-alpha-D-glucosyl-1,6-alpha-D-glucosyl-, and 1,3-1-O-alkyl-2-O-acylglycerol.

This enzyme belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:triglucosyl-1-O-alkyl-2-O-acylglycerol 6-sulfotransferase. This enzyme is also called triglucosylmonoalkylmonoacyl sulfotransferase.
