It also has a role in protecting cells from destruction because it produces a cofactor NADPH which plays a role in protecting cells from reactive oxygen species.

It is coded by the G6PD gene (1461 nucleotides).

D-glucose 6-phosphate + NAD+ → 6-phospho-D-glucono-1,5-lactone + H+ + NADH

KM=8.0 µM for NADP, KM=160 µM for NAD
 +
Its regulation depends on the concentration of substrate and coenzyme, rate limiting step in pentose phosphate pathway.

== Optimal activity conditions ==
 +
Optimum pH is 5.4 - 8.9.

== Evolutionary conservation ==

We will keep the interactivity that exist on the page: a box can be checked to observe the different structures conserved evolutionary.

== Mutations ==
 +
Mutagenesis inducing catalytic activity loss: +200 mutations have been identified. A change of amino acids leads to disruption of the normal

It is formed of a homodimer (dimer of two identical monomers).
 +
Depending on several conditions, it can dimerize to form tetramers. Each monomer in the complex has a substrate binding site that binds to G6P, and a catalytic coenzyme binding site that binds to NADP+/NADPH using the Rossman fold.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.

This Sandbox is Reserved from 25/11/2019, through 30/9/2020 for use in the course "Structural Biology" taught by Bruno Kieffer at the University of Strasbourg, ESBS. This reservation includes Sandbox Reserved 1091 through Sandbox Reserved 1115.
To get started:
  • Click the edit this page tab at the top. 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.
