Enzyme Information

5.3.1.28
D-sedoheptulose 7-phosphate isomerase.
based on mapping to UniProt Q5F5E3
D-sedoheptulose 7-phosphate = D-glycero-D-manno-heptose 7-phosphate.
-!- In Gram-negative bacteria the enzyme is involved in biosynthesis of ADP-L-glycero-beta-D-manno-heptose, which is utilized for assembly of the lipopolysaccharide inner core. -!- In Gram-positive bacteria the enzyme is involved in biosynthesis of GDP-D-glycero-alpha-D-manno-heptose, which is required for assembly of S-layer glycoprotein.
