HGL, a 379 amino acid residue-long lipase enzyme, possesses a catalytic arm consisting of residues Ser-153, His-353, and Asp-324 essential to the breakdown of lipids, coordinated with an oxyanion hole Leu-67 Gln-154 <ref name="dogs">PMID:20965171</ref>, that serves to stabilize the transition state. Structurally, the human gastric lipase exhibits a complex, coordinated conformation, where the "lid", residues 215-244 <ref name="dogs">PMID:20965171</ref>, of the lipase gives way to the hydrophobic areas both surrounding the active site and interfacing the lid, thought to draw lipids and promote docking <ref name="roussel" />. | HGL, a 379 amino acid residue-long lipase enzyme, possesses a catalytic arm <scene name='72/728060/Catalytic_elbow/1'>TextToBeDisplayed</scene> consisting of residues Ser-153, His-353, and Asp-324 essential to the breakdown of lipids, coordinated with an oxyanion hole Leu-67 Gln-154 <ref name="dogs">PMID:20965171</ref>, that serves to stabilize the transition state.
