IUBMB Enzyme Nomenclature


Accepted name: 6-deoxy-6-sulfo-D-fructose transketolase

Reaction: (1) 6-deoxy-6-sulfo-D-fructose + D-glyceraldehyde-3-phosphate = D-xylulose-5-phosphate + 4-deoxy-4-sulfo-D-erythrose
(2) 4-deoxy-4-sulfo-D-erythrulose + D-glyceraldehyde-3-phosphate = D-xylulose-5-phosphate + sulfoacetaldehyde

Other name(s): 6-deoxy-6-sulfo-erythrulose transketolase; sqwGH (gene name)

Systematic name: 6-deoxy-6-sulfo-D-fructose:D-glyceraldehyde-3-phosphate glycolaldehydetransferase

Comments: The enzyme, characterized from the bacterium Clostridium sp. MSTE9, is involved in a D-sulfoquinovose degradation pathway.
