The thermoacidophilic archaea Picrophilus torridus and Sulfolobus solfataricus catabolize glucose via a nonphosphorylative Entner-Doudoroff pathway and a branched Entner-Doudoroff pathway, respectively. Key enzymes for these Entner-Doudoroff pathways are the aldolases, 2-keto-3-deoxygluconate aldolase (KDG-aldolase) and 2-keto-3-deoxy-6-phosphogluconate aldolase [KD(P)G-aldolase]. KDG-aldolase from P.
