Hyaluronidase

spinqualitylabelsall models Hyaluronidase complex with hyaluronic acid disaccharide and dimethylarsinate, 1c82 Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Hyaluronidase (HU) hydrolyzes complex carbohydrates such as hyaluronan which is part of the extracellular matrix. The hydrolysis increases tissue permeability. Superposition of the EGF-like domain of hyaluronidase-1 (yellow) and the heparin-binding EGF-like growth factor (light blue). The three disulphide bonds of the EGF domains (highlighted red) exhibit the same pattern in the primary structure and are located in similar positions in the 3D structure. Hyaluronidase cleaves the β1,4-glycosidic bond of the glycosaminoglycan hyaluronan Relevance HU is used in medicine to speed drug delivery. Hyaluronic acid (HUA) is a popular dermal filler material. Structural highlights HU structure contains an N-terminal, linker and C-terminal domains. The active site is in a cleft in the N-terminal domain. Two HUA molecules are bound in the active site making contacts with some HU residues and multiple contacts with water molecules. 1st active site of HU. Water molecules shown as red spheres. 2nd active site of HU. Dimethylarsinate binding site.
