NADPH has been found to inhibit the enzyme noncompetitively with respect to NADP<sup>+</sup>, and uncompetitively with respect to glucose 6-phosphate.

An attempt was made to estimate the in vivo activities of the two enzymes in rat liver in the presence of NADPH at various NADPH/NADP<sup>+</sup> ratios.
