EC 3.1.3.82     
Accepted name: D-glycero-β-D-manno-heptose 1,7-bisphosphate 7-phosphatase
Reaction: D-glycero-β-D-manno-heptose 1,7-bisphosphate + H2O = D-glycero-β-D-manno-heptose 1-phosphate + phosphate
Other name(s): gmhB (gene name); yaeD (gene name)
Systematic name: D-glycero-β-D-manno-heptose 1,7-bisphosphate 7-phosphohydrolase
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].
