Fructose-1,6-bisphosphate aldolase. The enzyme catalyzes the cleavage of fructose 1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP). This family includes proteins found in vertebrates, plants, and bacterial plant pathogens. Mutations in the aldolase genes in humans cause hemolytic anemia and hereditary fructose intolerance. The enzyme is a member of the class I aldolase family, which utilizes covalent catalysis through a Schiff base formed between a lysine residue of the enzyme and ketose substrates.
