NADP⁺ content bound to purified FNR enzymes from different organisms

Enzyme	NADP+/FNR (mol/mol)
EcFPR	0.99 ± 0.05
PcFPR	0.65 ± 0.05
BaFPR	0.30 ± 0.02
LepFNR	0.16 ± 0.03
PeaFNR	0.08 ± 0.03

Note: The NADP⁺ content was determined by the reaction of the G6PD activity in 50 mM Tris–HCl, pH 8.0, at 25°C. Values are mean ± SD of at least three independent measurements.
