SYSTEMATIC NAME
IUBMB Comments
NADPH:hemoprotein oxidoreductase
A flavoprotein (FMN, FAD) containing both FMN and FAD. The number n in the equation is 1 if the hemoprotein undergoes a 2-electron reduction, and is 2 if it undergoes a 1-electron reduction. The enzyme catalyses the reduction of the heme-thiolate-dependent monooxygenases, such as EC 1.14.14.1, unspecific monooxygenase and reduction of EC 1.14.99.3, heme oxygenase (biliverdin-producing). It is part of the microsomal hydroxylating system. It also reduces cytochrome b5 and cytochrome c.

evolution
-
Spodoptera littoralis P450s belong to four clades defined by their conservation with vertebrate P450s and their cellular localization
evolution
-
the enzyme is a member of the diflavin oxidoreductase family. They are multi-domain enzymes containing distinct FAD and FMN domains connected by a flexible hinge. The protein has evolved by fusing two ancestral genes that encode proteins related to a FMN-containing flavodoxin and a FAD-containing ferredoxin-NADP+ oxidoreductase

physiological function
R4UB73
NADPH-cytochrome P450 reductase is one of the most important components of the cytochrome P450 enzyme system. It catalyzes electron transfer from NADPH to all known P450s, thus plays central roles not only in the metabolism of exogenous xenobiotics but also in the regulation of endogenous hormones in insects

physiological function
-
regulation of the CPR gene by odorants within insect antennae
physiological function
-
the enzyme is capable of activating molecular oxygen on its own merit, generating diffusible reduced oxygen species. It deplete peroxide via diffusible radical mediated process, thereby leading to the formation of water (but without significant evolution of oxygen). CPR mediated processes are bound to be energetically wasteful and potentially hazardous owing to the unavoidable nature of the CPR to generate and deplete diffusible reduced oxygen species.

additional information
P00388
the electron transfer pathway in CYPOR begins with the obligate two electron donor, NADPH, which transfers a hydride ion to FAD, which in turn donates electrons to the FMN cofactor. The FMN hydroquinone then transfers electrons, one at a time, to its redox partners. Comparison of the structures without and with NADP+ shows movement of the Gly631-Asn635 loop. In the NADP+-free structure, the loop adopts a conformation that sterically hinders NADP(H) binding. The structure with NADP+ shows movement of the Gly631-Asn635 loop to a position that permits NADP(H) binding. Comparison of mutant and wild-type structures, overview. The Gly631-Asn635 loop movement controls NADPH binding and NADP+ release, this loop movement in turn facilitates the flavin domain movement, allowing electron transfer from FMN to the CYPOR redox partners

P450R function is essential for cytochrome P450 activity. The enzyme provides the electrons used in P450-mediated reactions using NADPH as a cofactor. P450R-transfected MDA 231 breast cells display increased sensitivity to mitomycin C and 5-fluorouracil as compared to their empty-vector transfected counterparts. NADPH levels are decreased in P450R-overexpressing cells

the presence of NADPH-cytochrome P450 reductase prevents heme oxygenase-1 from acetylation of lysine residues, Lys149 and Lys153, located in the F-helix. The heme degradation activity of the fully acetylated heme oxygenase-1 in the NADPH/NADPH-cytochrome P450 reductase-supported system is significantly reduced, whereas almost no inactivation is detected in heme oxygenase-1 in the presence of NADPH-cytochrome P450 reductase, which prevents acetylation of Lys149 and Lys153

the presence of NADPH-cytochrome P450 reductase prevents heme oxygenase-1 from acetylation of lysine residues, Lys149 and Lys153, located in the F-helix. The heme degradation activity of the fully acetylated heme oxygenase-1 in the NADPH/NADPH-cytochrome P450 reductase-supported system is significantly reduced, whereas almost no inactivation is detected in heme oxygenase-1 in the presence of NADPH-cytochrome P450 reductase, which prevents acetylation of Lys149 and Lys153

second FMN binding site is detected at the interface of the connecting and FMN binding domains. The two FMN binding sites have different accessibilities to the bulk solvent and different amino acid environments, suggesting stabilization of different electronic structures of the reduced flavin. Since only one FMN cofactor is required for function, a hypothetical mechanism of electron transfer is discussed that proposes shuttling of a single FMN between these two sites coupled with the transition between two semiquinone forms, neutral and anionic

In contrast, at high molar ratios of cytochome b5 to cytochrome P450 reductase, cytochrome b5 inhibits activity by binding to the proximal surface of cytochrome P450 and preventing the reductase from reducing ferric cytochrome P450 to the ferrous protein, thereby aborting the catalytic reaction cycle. Cytochrome b5 stimulates catalysis by causing a conformational change in the active site, which allows the active oxidizing oxyferryl species of cytochrome P450 to be formed more rapidly than in the presence of reductase

physical incorporation of NADPH-cytochrome P450 reductase and cytochrome P450 into phospholipid vesicles using glycocholate and Bio-Beads. The efficiency of incorporation of reductase and CYP2B4 is examined in reconstituted systems prepared by the detergent-dialysis method as a function of the detergent used
additional information
-
The substitution mutants (E238A/E239A and T236A/G237A/E238A/E239A) exhibit wild-type activity with cytochrome c. The 2- and 4-alanine addition mutants exhibit about 50% increase in activity compared with the wild-type enzyme. The two and four amino acid deletion mutants reduce cytochrome c 6.4- and 214-fold slower than wild type, respectively.

CPR activity in 28-day-old male offspring in only the LM76 group (low protein diet based on the modified version of the AIN76A purified diet) but not in the L93 group (low protein diet based on the AIN93G purified diet) is significantly greater than its purified control. CPR activity in 28-day-old male offspring of the M76 group is lower than that in the NP group (nonpurified diet). CPR activities in 65- and 150-day-old male offspring in all five groups are similar. CPR activities in 28-day-old female offspring of the LPD groups are similar to those of their respective purified control groups. However, CPR activities in 28-day-old female offspring in both the purified control groups are lower than that in the NP group. These differences disappeare by day 65, and the lack of differences persisted on day 150. Gender differences (activity in males greater than that in females) are present in all five groups on day 150 but not on days 28 and 65 (the 28-day-old NP group being an exception)

Crystals are flash-frozen in liquid nitrogen using 10% PEG 200 as cryoprotectant. Crystal structures of the mutant haem domains demonstrate axial ligation of P450 haem iron by methionine and glutamine ligands trans to the cysteine thiolate, creating novel haem iron ligand sets in the A264M/Q variants

NADPH-cytochrome c oxidoreductase lacking the first 55 amino acid residues (DELTA55AnCY) is expressed in Escherichia coli loses FMN, leading to an unstable protein and subsequent aggregation. The triple mutant L86F/L219F/P456FDELTA55AnCY exhibits increased stability with significant reduction in aggregation compared to the wild-type enzyme

variants of Depressaria pastinacella CYP6AB3v2 are co-expressed with P450 reductase from Musca domestica in Sf9 cells. Allelic variation in the Depressaria pastinacella CYP6AB3 protein enhances metabolism of plant allelochemicals by altering a proximal surface residue and potential interactions with cytochrome P450 reductase

to analyze the molecular interaction among CYP3A4, NADPH-cytochrome P450 oxidoreductase, and b5, several fused enzyme genes are constructed and expressed in Saccharomyces cerevisiae. The recombinant fused enzymes CYP3A4-truncated(t)-P450 reductase-t-b5 (3RB) and CYP3A4-t-b5-t-P450 reductase (3BR) in yeast microsomes shows a higher specific activity in 6beta-hydroxylation of testosterone than does the reconstitution premixes of CYP3A4, P450 reductase, and b5. The purified fused enzymes exhibit lower Km values and substantially increased Vmax values in 6beta-hydroxylation of testosterone and oxidation of nifedipine. The fused enzymes shows significantly higher activities in cytochrome c reduction than the reconstitution premixes. Although the affinity of 3RB toward cytochrome c is twice as high as that of 3BR, 3BR and 3RB show nearly the same affinity toward NADPH/NADH. In addition, the heme of the CYP3A4 moiety of 3RB is reduced preferentially and more rapidly than that of 3BR, whereas the heme of the b5 moiety of 3BR is selectively reduced compared with that of 3RB
