IntEnz Enzyme Nomenclature
EC 3.1.3.82

Names

Accepted name:
D-glycero-β-D-manno-heptose 1,7-bisphosphate 7-phosphatase
Other names:
gmhB (gene name)
yaeD (gene name)
Systematic name:
D-glycero-β-D-manno-heptose 1,7-bisphosphate 7-phosphohydrolase

Reaction

Comments:

The enzyme is involved in biosynthesis of ADP-L-glycero-β-D-manno-heptose, which is utilized for assembly of the lipopolysaccharide inner core in Gram-negative bacteria. In vitro the catalytic efficiency with the β-anomer is 100-200-fold higher than with the α-anomer [3].
