Function

[Q97U29_SULSO] Involved in the degradation of glucose and galactose via the semi-phosphorylative Entner-Doudoroff pathway. Catalyzes the phosphorylation of 2-keto-3-deoxygluconate (KDG) and 2-keto-3-deoxygalactonate (KDGal) to produce 2-keto-3-deoxy-6-phosphogluconate (KDPG) and 2-keto-3-deoxy-6-phosphogalactonate (KDPGal), respectively.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The hyperthermophilic archaeon Sulfolobus solfataricus grows optimally above 353 K and utilizes an unusual promiscuous nonphosphorylative Entner-Doudoroff pathway to metabolize both glucose and galactose. It has been proposed that a part-phosphorylative Entner-Doudoroff pathway occurs in parallel in S. solfataricus, in which the 2-keto-3-deoxygluconate kinase (KDGK) is promiscuous for both glucose and galactose metabolism. Recombinant S. solfataricus KDGK protein was expressed in Escherichia coli, purified and crystallized in 0.1 M sodium acetate pH 4.1 and 1.4 M NaCl. The crystal structure of apo S. solfataricus KDGK was solved by molecular replacement to a resolution of 2.0 A and a ternary complex with 2-keto-3-deoxygluconate (KDGlu) and an ATP analogue was resolved at 2.1 A. The complex suggests that the structural basis for the enzyme's ability to phosphorylate KDGlu and 2-keto-3-deoxygalactonate (KDGal) is derived from a subtle repositioning of residues that are conserved in homologous nonpromiscuous kinases.
