In enzymology a formaldehyde transketolase (EC 2.2.1.3) is an enzyme that catalyzes the chemical reactionD-xylulose 5-phosphate + formaldehyde glyceraldehyde 3-phosphate + glyceroneThus the two substrates of this enzyme are D-xylulose 5-phosphate and formaldehyde whereas its two products are glyceraldehyde 3-phosphate and glycerone.This enzyme belongs to the family of transferases specifically those transferring aldehyde or ketonic groups (transaldolases and transketolases respectively).
