MGL has eight-stranded β-sheet protein fold with seven parallel and one <scene name='58/580299/Beta_sheets/1'> antiparallel strand </scene> (Bertrand et al. 2010).
MGL has eight-stranded β-sheet protein fold with seven parallel and one <scene name='58/580299/Beta_sheets/1'> antiparallel strand </scene> (Bertrand et al. 2010). The β-sheets are surrounded by α-helices.  The combination of the α-helices and β-sheets are able to provide a stable scaffold for the active sites within MGL (Bertrand et al. 2010). Within the main domain of MGL is the conserved catalytic triad (Bertrand et al. 2010).

The ligand binding pocket of MGL has a large hydrophobic region with a polar bottom (Bertrand et al. 2010).  Bertrand found that in MGL the binding pocket is not adjusted to the ligands shape.  2-archidonylglycerol are ligands for cannabinoid receptors (Clemente et al. 2012).  Inhibition of MGL leads to increase in 2-AG levels since AG is broken down by MGL (Clemente et al. 2012).  Through covalent interactions with a Cys residue, NAM, one of the many possible inhibitors, is able to inhibit MGL (Bertrand et al. 2010). <scene name='58/580298/Ligand/1'>Lignad binding site</scene>
The ligand binding pocket of MGL has a large hydrophobic region with a polar bottom (Bertrand et al. 2010).  The entrance of the binding pocket for MGL contains a lid, which is very flexible (Bertrand et al. 2010).  Bertrand found that in MGL the binding pocket is not adjusted to the ligands shape.  2-archidonylglycerol are ligands for cannabinoid receptors (Clemente et al. 2012).  Inhibition of MGL leads to increase in 2-AG levels since AG is broken down by MGL (Clemente et al. 2012).  Through covalent interactions with a Cys residue, NAM, one of the many possible inhibitors, is able to inhibit MGL (Bertrand et al. 2010). <scene name='58/580298/Ligand/1'>Lignad binding site</scene>
