2.5 A resolution, alpha-beta-protein, carbohydrate attached to Asn18, active centre close to His 131

H134 and H252 involved in catalysis

in complex with magnesium and phosphate ions, both bound in the active site, to 1.95 A resolution. Data suggest a magnesium-assisted pentavalent phosphate transition state during catalysis, where Asp168 may play a key role as a general catalytic base. Residue Asn7 plays a critical role in the catalytic mechanism, participating indirectly in the coordination sphere of the Mg2+ ion with an H-bond of its amide oxygen with a coordinated water molecule and connects Asp168 and Glu39 with an H-bonding network via its amide nitrogen
