DE   gluconate/galactonate dehydratase.
AN   gluconate dehydratase.
CA   (1) D-gluconate = 2-dehydro-3-deoxy-D-gluconate + H2O.
CA   (2) D-galactonate = 2-dehydro-3-deoxy-D-galactonate + H2O.
CC   -!- The enzyme is involved in glucose and galactose catabolism via the
CC       nonphosphorylative variant of the Entner-Doudoroff pathway in
CC       Picrophilus torridus and via the branched variant of the Entner-
CC       Doudoroff pathway in Sulfolobus solfataricus.
CC   -!- In vitro it utilizes D-gluconate with 6-10 fold higher catalytic
CC       efficiency than D-galactonate. cf. EC 4.2.1.6 and EC 4.2.1.39.
