The enzyme fructose-6-phosphate phosphoketolase (EC 4.1.2.22) catalyzes the chemical reaction
- D-fructose 6-phosphate + phosphate [math]\displaystyle{ \rightleftharpoons }[/math] acetyl phosphate + D-erythrose 4-phosphate + H2O
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 D-fructose-6-phosphate D-erythrose-4-phosphate-lyase (adding phosphate; acetyl-phosphate-forming). Other names in common use include D-fructose-6-phosphate D-erythrose-4-phosphate-lyase, and (phosphate-acetylating). This enzyme participates in pentose phosphate pathway.
