Description

Structure of homodimeric human renal dipeptidase complexed with cilastatin. Both monomers are bound by a disulfide bridge with Cys377.
The catalytic site of this protease contains two Zn atoms (shown as a golden spheres). Zinc 1 is complexed by His36 and Asp38, whereas zinc 2 is complexed by His214 and His235. On the other hand, Glu141 forms a "bridge" and complexes both atoms. According to its position, the putative general base which attacks the target peptidic bond depends on Asp304.

Instructions

  • Structures are rendered as ribbons. Catalytic and catalytic metal-complexing residues are shown as neons. Inhibitors are displayed as space filling spheres.

  • Carbons are shown in light gray, hydrogens in cyan, oxygens in red, nitrogens in blue, and sulfurs in yellow.

  • Left-click and drag to rotate the protease. Right-click and drag up/down to zoom in/out. Click with both buttons and drag to move the protease. Use the upper bar to get different views and for display options. For a close-up of the catalytic site, choose the cat_site view.

  • Once you have clicked inside the structure window, you can use the keyboard to hide/show objects:

    '1' toggles the ribbon.
    '2' toggles the inhibitor.
    '3' toggles the catalytic residues.

  • To display and manipulate the structure, you need at least Adobe Acrobat Reader v7.0. For best results, install the last version of Acrobat Reader.

  • To hide/show elements in the structure, first you have to click inside the render window.
