Protein

D-galactonate dehydratase family member Dd703_0947

Gene

Dd703_0947

Organism
Dickeya paradisiaca (strain Ech703) (Dickeya dadantii (strain Ech703))
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Has low dehydratase activity with D-mannonate and D-gluconate, suggesting that these are not physiological substrates and that it has no significant role in the in vivo degradation of these compounds. Has no detectable activity with a panel of 70 other acid sugars (in vitro).1 Publication

Catalytic activityi

D-mannonate = 2-dehydro-3-deoxy-D-gluconate + H2O.1 Publication
D-gluconate = 2-dehydro-3-deoxy-D-gluconate + H2O.1 Publication

Cofactori

Mg2+1 PublicationNote: Binds 1 Mg2+ ion per subunit.1 Publication

Kineticsi

kcat is 0.04 sec(-1) with D-mannonate. kcat is 0.03 sec(-1) with D-gluconate.1 Publication
