Promiscuity in the part-phosphorylative Entner-Doudoroff pathway of the archaeon Sulfolobus solfataricus.
Lamble H.J., Theodossis A., Milburn C.C., Taylor G.L., Bull S.D., Hough D.W., Danson M.J.

The hyperthermophilic archaeon Sulfolobus solfataricus metabolises glucose and galactose by a 'promiscuous' non-phosphorylative variant of the Entner-Doudoroff pathway, in which a series of enzymes have sufficient substrate promiscuity to permit the metabolism of both sugars. Recently, it has been proposed that the part-phosphorylative Entner-Doudoroff pathway occurs in parallel in S. solfataricus as an alternative route for glucose metabolism. In this report we demonstrate, by in vitro kinetic studies of D-2-keto-3-deoxygluconate (KDG) kinase and KDG aldolase, that the part-phosphorylative pathway in S. solfataricus is also promiscuous for the metabolism of both glucose and galactose. << Less

Characterization of Sulfolobus solfataricus 2-keto-3-deoxy-D-gluconate kinase in the modified Entner-Doudoroff pathway.
Kim S., Lee S.B.
The thermoacidophilic archaeon Sulfolobus solfataricus is known to utilize D-glucose via the nonphosphorylated Entner-Doudoroff (ED) pathway. But, the genome database shows that this microorganism has a gene (kdgK) encoding 2-keto-3-deoxy-D-gluconate (KDG) kinase (KDGK) which phosphorylates KDG to ... >> More
The thermoacidophilic archaeon Sulfolobus solfataricus is known to utilize D-glucose via the nonphosphorylated Entner-Doudoroff (ED) pathway. But, the genome database shows that this microorganism has a gene (kdgK) encoding 2-keto-3-deoxy-D-gluconate (KDG) kinase (KDGK) which phosphorylates KDG to 2-keto-3-deoxy-6-phosphogluconate. Interestingly, kdgK and three other genes in the modified ED pathway are organized as an operon-like structure. In this study, we report confirmation of the catalytic activity of the S. solfataricus KDGK protein. We also found that the kdgK gene was transcribed as polycistronic transcripts. Proteome analysis of cell lysate revealed that all gene products in the kdgK operon were expressed as functional proteins. These results strongly indicate that S. solfataricus metabolizes D-glucose via the 'partially' nonphosphorylated ED pathway. A purified recombinant S. solfataricus KDGK had K(m) and k(cat) values of 0.14 mM and 60.8 s(-1) respectively for KDG, and showed maximal activity at temperatures between 70 and 80 degrees C and pHs between 7.0 and 8.0. << Less
