Galactonate dehydratase

The enzyme galactonate dehydratase catalyzes the chemical reaction


 * D -galactonate $$\rightleftharpoons$$ 2-dehydro-3-deoxy- D -galactonate + H2O

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is  D -galactonate hydro-lyase (2-dehydro-3-deoxy- D -alactonate-forming). Other names in common use include  D -galactonate dehydrase,  D -galactonate dehydratase, and  D -galactonate hydro-lyase. This enzyme participates in galactose metabolism.
