Crystal structures of InhA reveal a <scene name='69/694241/Homotetramer_subunits_labeled/1'>homotetramer</scene> (each subunit featured with a different color) in aqueous solution with separate ligand binding sites in each subunit. Each <scene name='69/694241/Monomer_subunit_no_ligands/1'>monomer</scene> subunit is composed of 289 residues and features a typical [http://en.wikipedia.org/wiki/Rossmann_fold] containing a single NADH binding site. The <scene name='69/694241/Secondary_structure_black/1'>secondary structure</scene> of InhA is made up of several alpha helices (pink), beta sheets (gold), and beta turns (white). This enzyme also features a fatty acyl binding crevice that accommodates the long-chain fatty acyl substrate (2TK) needed to synthesize mycolic acid precursors. The <scene name='69/694241/Helix6_helix7_updated/1'>alpha-6 and alpha-7 helices</scene> of the InhA form one side of the fatty acyl binding crevice, referred to as the <scene name='69/694241/Monomer_subunit_196_219/1'> substrate binding loop</scene> (residues 196-219).

=== '''Fatty Acyl Binding Crevice''' ===

Within the fatty acyl binding crevice, the NADH substrate sits on the top shelf of the Rossmann fold, and the fatty acyl substrate sits on top of the NADH substrate. Both of these substrates are held in place through interactions with the hydrophobic residues in the substrate binding loop. [[Image:Binding Pocket - Mesh.jpg|thumb|250px|right|Substrate Binding Pocket (NADH in green; fatty acyl substrate in red)]] One side of this crevice is open and exposed to solvent, which allows the substrates to access the binding pocket of this enzyme. The size of the substrate binding loop is a primary determinant of the ability of InhA to distinguish between shorter and longer substrates and provide <scene name='69/694241/Substrate_binding_pocket/1'>specificity</scene> for the enoyl-ACP reductase reaction.

This Sandbox is Reserved from 02/09/2015, through 05/31/2016 for use in the course "CH462: Biochemistry 2" taught by Geoffrey C. Hoops at the Butler University. This reservation includes Sandbox Reserved 1051 through Sandbox Reserved 1080.
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.
