The enzyme ketotetrose-phosphate aldolase (EC 4.1.2.2) catalyzes the chemical reaction
- erythrulose 1-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] glycerone phosphate + formaldehyde
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.
