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.

== Disease ==
== Genomic context ==  
It is coded by the G6PD gene (1461 nucleotides).


== Relevance ==
== Catalytic activity ==
D-glucose 6-phosphate + NAD+ → 6-phospho-D-glucono-1,5-lactone + H+ + NADH
KM=114 µM for G6PD (with NADP), KM=69 µM for G6PD (with NAD),
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
structure/function/reduce the expression of enzymes.


== Structural highlights ==
== Structural highlights ==
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.
