in diverse anaerobic bacteria including Firmicutes, Tenericutes, Spirochaetes, and Thermotogae bacteria, a sulfoquinone degradation pathway contains a mutarotase SqvB, an isomerase SqvD, a transketolase SqwGH, a homologue of ribose-5-phosphate isomerase SqwI, a metal-dependent alcohol dehydrogenase SqwF, and a member of the sulfite/sulfonate exporter family SqwE. This suggests a pathway involving isomerization of sulfoquinone to 6-deoxy-6-sulfofructose by SqvD, cleavage of 6-deoxy-6-sulfofructose by SqwGH, reduction of an aldehyde-containing sulfonate by SqwF, followed by export of the sulfonate end-product by SqwE |
