Reaction: 6-deoxy-6-sulfo-D-fructose + D-glyceraldehyde 3-phosphate = (2S)-3-sulfolactaldehyde + β-D-fructofuranose 6-phosphate
Glossary: (2S)-3-sulfolactaldehyde = (2S)-2-hydroxy-3-oxopropane-1-sulfonate
Other name(s): sftT (gene name)
Systematic name: 6-deoxy-6-sulfo-D-fructose:D-glyceraldehyde-3-phosphate glyceronetransferase
Comments: The enzyme, characterized from the bacterium Bacillus aryabhattai SOS1, is involved in a degradation pathway for 6-sulfo-D-quinovose. The enzyme can also use D-erythrose 4-phosphate as the acceptor, forming D-sedoheptulose 7-phosphate.
