EC 1.2.1.97     
Accepted name: 3-sulfolactaldehyde dehydrogenase
Reaction: (2S)-3-sulfolactaldehyde + NAD(P)+ + H2O = (2S)-3-sulfolactate + NAD(P)H + H+
Glossary: (2S)-3-sulfolactaldehyde = (2S)-2-hydroxy-3-oxopropane-1-sulfonate
Other name(s): SLA dehydrogenase
Systematic name: (2S)-3-sulfolactaldehyde:NAD(P)+ oxidoreductase
Comments: The enzyme, characterized from the bacterium Pseudomonas putida SQ1, participates in a sulfoquinovose degradation pathway. Also acts on succinate semialdehyde.

EC 2.2.1.14     
Accepted name: 6-deoxy-6-sulfo-D-fructose transaldolase
Reaction: 6-deoxy-6-sulfo-D-fructose + D-glyceraldehyde 3-phosphate = (2S)-3-sulfolactaldehyde + β-D-fructofuranose 6-phosphate
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.
