The enzyme 2-dehydro-3-deoxyglucarate aldolase (EC 4.1.2.20) catalyzes the chemical reaction
- 2-dehydro-3-deoxy-D-glucarate [math]\displaystyle{ \rightleftharpoons }[/math] pyruvate + tartronate semialdehyde
This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 2-dehydro-3-deoxy-D-glucarate tartronate-semialdehyde-lyase (pyruvate-forming). Other names in common use include 2-keto-3-deoxyglucarate aldolase, alpha-keto-beta-deoxy-D-glucarate aldolase, and 2-dehydro-3-deoxy-D-glucarate tartronate-semialdehyde-lyase. This enzyme participates in ascorbate and aldarate metabolism.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1DXE, 1DXF, 1W37, 1W3I, 1W3N, and 1W3T.
