Ketotetrose phosphate aldolase

In enzymology, a ketotetrose-phosphate aldolase (EC 4.1.2.2) is an enzyme that 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.
