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. |
