Other name(s): Pto1279 (gene name); KDGA; KDG-specific aldolase

Systematic name: 2-dehydro-3-deoxy-D-gluconate D-glyceraldehyde-lyase (pyruvate-forming)

Comments: The enzyme from the archaeon Picrophilus torridus is involved in D-glucose and D-galactose catabolism via the nonphosphorylative variant of the Entner-Doudoroff pathway. In the direction of aldol synthesis the enzyme catalyses the formation of 2-dehydro-3-deoxy-D-gluconate and 2-dehydro-3-deoxy-D-galactonate at a similar ratio. It shows no activity with 2-dehydro-3-deoxy-D-gluconate 6-phosphate. cf. EC, 2-dehydro-3-deoxy-phosphogluconate aldolase.
