This Sandbox is Reserved from August 30, 2022 through May 31, 2023 for use in the course Biochemistry I taught by Kimberly Lane at the Radford University, Radford, VA, USA. This reservation includes Sandbox Reserved 1730 through Sandbox Reserved 1749.
To get started:
  • Click the edit this page tab at the top. Click on Show preview and then Save the page after each step, then edit it again.
  • 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.

Structure

Drag the structure with the mouse to rotate

Primary Structure: ~461 amino acids

Secondary Structure: 12 alpha helicies, 12 beta strands

Tertiary Structure: N-Terminal Regulatory Domain, C-Terminal Catalytic Domain

Quaternary Structure: Forms a homodimer

Function

Glucose binds to hexokinase, which is then attacked by ATP. The terminal phosphate group on the ATP binds to the glucose, creating two products: glucose-6-phosphate, and ADP. Hexokinase serves as a catalyst for this reaction.

This is a sample scene created with SAT to by Group, and another to make of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
