Formaldehyde transketolase (EC 2.2.1.3) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are D-xylulose 5-phosphoric acid and formaldehyde. Its products are glyceraldehyde 3-phosphate and dihydroxyacetone. The enzyme was characterised from the yeast Candida boidinii [1][2][3]
This enzyme belongs to the family of transferases, specifically those transferring aldehyde or ketonic groups (transaldolases and transketolases, respectively). The systematic name of this enzyme class is D-xylulose-5-phosphate:formaldehyde glycolaldehydetransferase. This enzyme is also called dihydroxyacetone synthase. It uses thiamin diphosphate as a cofactor.[4]
