D-sedoheptulose 7-phosphate isomerase

D-sedoheptulose 7-phosphate isomerase (, "sedoheptulose-7-phosphate isomerase", "phosphoheptose isomerase", "gmhA (gene)", "lpcA (gene)") is an enzyme with systematic name "D-glycero-D-manno-heptose 7-phosphate aldose-ketose-isomerase". This enzyme catalyses the following chemical reaction
In Gram-negative bacteria the enzyme is involved in biosynthesis of ADP-L-glycero-β-D-manno-heptose.
