EC 3.1.3.83     
Accepted name: D-glycero-α-D-manno-heptose 1,7-bisphosphate 7-phosphatase
Reaction: D-glycero-α-D-manno-heptose 1,7-bisphosphate + H2O = D-glycero-α-D-manno-heptose 1-phosphate + phosphate
Other name(s): gmhB (gene name)
Systematic name: D-glycero-α-D-manno-heptose 1,7-bisphosphate 7-phosphohydrolase
Comments: The enzyme is involved in biosynthesis of GDP-D-glycero-α-D-manno-heptose, which is required for assembly of S-layer glycoprotein in some Gram-positive bacteria. The in vitro catalytic efficiency of the enzyme from Bacteroides thetaiotaomicron is 6-fold higher with the α-anomer than with the β-anomer [1].
