CC -!- FUNCTION: Catalyzes the reversible retro-aldol cleavage of both 5-keto-
CC 4-deoxy-D-glucarate and 2-keto-3-deoxy-D-glucarate to pyruvate and
CC tartronic semialdehyde. {ECO:0000255|HAMAP-Rule:MF_01291}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-dehydro-4-deoxy-D-glucarate = 2-hydroxy-3-oxopropanoate +
CC pyruvate; Xref=Rhea:RHEA:27726, ChEBI:CHEBI:15361, ChEBI:CHEBI:42819,
CC ChEBI:CHEBI:57978; Evidence={ECO:0000255|HAMAP-Rule:MF_01291};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-dehydro-3-deoxy-D-glucarate = 2-hydroxy-3-oxopropanoate +
CC pyruvate; Xref=Rhea:RHEA:10268, ChEBI:CHEBI:15361, ChEBI:CHEBI:57978,
CC ChEBI:CHEBI:58098; EC=4.1.2.20; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01291};
CC -!- COFACTOR:

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01291};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01291};
CC -!- PATHWAY: Carbohydrate acid metabolism; galactarate degradation; D-
CC glycerate from galactarate: step 2/3. {ECO:0000255|HAMAP-
CC Rule:MF_01291}.
CC -!- SUBUNIT: Homohexamer; trimer of dimers. {ECO:0000255|HAMAP-
CC Rule:MF_01291}.
CC -!- SIMILARITY: Belongs to the HpcH/HpaI aldolase family. KDGluc aldolase
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01291}.
