The enzyme ketotetrose-phosphate aldolase (EC 4.1.2.2) catalyzes the chemical reaction
Hence, this enzyme has one substrate, erythrulose 1-phosphate, and two products, dihydroxyacetone phosphate and formaldehyde.
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 erythrulose-1-phosphate formaldehyde-lyase (glycerone-phosphate-forming). Other names in common use include phosphoketotetrose aldolase, erythrulose-1-phosphate synthetase, erythrose-1-phosphate synthase, and erythrulose-1-phosphate formaldehyde-lyase.
In biochemistry, a lyase is an enzyme that catalyzes the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or a new ring structure. The reverse reaction is also possible. For example, an enzyme that catalyzed this reaction would be a lyase:

3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase is the first enzyme in a series of metabolic reactions known as the shikimate pathway, which is responsible for the biosynthesis of the amino acids phenylalanine, tyrosine, and tryptophan. Since it is the first enzyme in the shikimate pathway, it controls the amount of carbon entering the pathway. Enzyme inhibition is the primary method of regulating the amount of carbon entering the pathway. Forms of this enzyme differ between organisms, but can be considered DAHP synthase based upon the reaction that is catalyzed by this enzyme.
