CC   -!- FUNCTION: Catalyzes the dehydration of D-galactonate to 2-keto-3-deoxy-
CC       D-galactonate. {ECO:0000255|HAMAP-Rule:MF_01289}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-galactonate = 2-dehydro-3-deoxy-D-galactonate + H2O;
CC         Xref=Rhea:RHEA:18649, ChEBI:CHEBI:12931, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:57989; EC=4.2.1.6; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01289};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01289};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01289};
CC   -!- PATHWAY: Carbohydrate acid metabolism; D-galactonate degradation; D-
CC       glyceraldehyde 3-phosphate and pyruvate from D-galactonate: step 1/3.
CC       {ECO:0000255|HAMAP-Rule:MF_01289}.
CC   -!- MISCELLANEOUS: Reaction proceeds via an anti dehydration.
CC       {ECO:0000255|HAMAP-Rule:MF_01289}.
CC   -!- SIMILARITY: Belongs to the mandelate racemase/muconate lactonizing
CC       enzyme family. GalD subfamily. {ECO:0000255|HAMAP-Rule:MF_01289}.
