The enzyme 2-dehydro-3-deoxy-<small>D</small>-pentonate aldolase () catalyzes the chemical reaction
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-pentonate glycolaldehyde-lyase (pyruvate-forming). Other names in common use include 2-keto-3-deoxy-D-pentonate aldolase, 3-deoxy-D-pentulosonic acid aldolase, and 2-dehydro-3-deoxy-D-pentonate glycolaldehyde-lyase. This enzyme participates in pentose and glucuronate interconversions.
