Other name(s): (R)-sulfolactate:NADP+ oxidoreductase; L-sulfolactate dehydrogenase; (R)-sulfolactate dehydrogenase; ComC
Systematic name: (2R)-3-sulfolactate:NADP+ oxidoreductase
Comments: The enzyme from the bacterium Chromohalobacter salexigens can only utilize NADP+. It functions both biosynthetically in coenzyme M biosynthesis and degradatively, in the degradation of sulfolactate. It can not use (S)-malate and (S)-lactate.
