General annotation (Comments)

Catalytic activity

4-hydroxy-2-oxoglutarate = pyruvate + glyoxylate.

2-dehydro-3-deoxy-6-phosphate-D-gluconate = pyruvate + D-glyceraldehyde 3-phosphate.

Pathway

Carbohydrate acid metabolism; 2-dehydro-3-deoxy-D-gluconate degradation; D-glyceraldehyde 3-phosphate and pyruvate from 2-dehydro-3-deoxy-D-gluconate: step 2/2.

Carbohydrate metabolism; glyoxylate and dicarboxylate metabolism.

Subunit structure

Homotrimer By similarity.

Subcellular location

Cytoplasm By similarity.

Miscellaneous

It also catalyzes the beta-decarboxylation of oxaloacetate By similarity.

Sequence similarities

Belongs to the KHG/KDPG aldolase family.
