Comments [?]

Function Catalyzes the reversible retro-aldol cleavage of both 5-keto-4-deoxy-D-glucarate and 2-keto-3-deoxy-D-glucarate to pyruvate and tartronic semialdehyde.
Catalytic activity RHEA:27726: 5-dehydro-4-deoxy-D-glucarate = 2-hydroxy-3-oxopropanoate + pyruvate
RHEA:10268: 2-dehydro-3-deoxy-D-glucarate = 2-hydroxy-3-oxopropanoate + pyruvate
EC 4.1.2.20
case <FTGroup:1>
Cofactor Mg(2+)
Note: Binds 1 Mg(2+) ion per subunit.
end case
Pathway Carbohydrate acid metabolism; galactarate degradation; D-glycerate from galactarate: step 2/3.
Subunit Homohexamer; trimer of dimers.
Similarity Belongs to the HpcH/HpaI aldolase family. KDGluc aldolase subfamily.
