Enzyme Information

5.3.1.27
6-phospho-3-hexuloisomerase.
based on mapping to UniProt P42404
D-arabino-hex-3-ulose 6-phosphate = D-fructose 6-phosphate.
-!- This enzyme, along with EC 4.1.2.43, plays a key role in the ribulose-monophosphate cycle of formaldehyde fixation, which is present in many microorganisms that are capable of utilizing C1-compounds. -!- The hyperthermophilic and anaerobic archaeon Pyrococcus horikoshii OT3 constitutively produces a bifunctional enzyme that sequentially catalyzes the reactions of EC 4.1.2.43 and this enzyme.
