Cytochrome P450 2S1 is reduced by NADPH-cytochrome P450 reductase.
Cytochrome P450 (P450) 2S1 is one of the orphan P450s without a clear physiological function. Controversy has arisen as to whether it can interact with NADPH-P450 reductase and accept electrons. The reduction of 1,4-bis{[2-(dimethylamino-N-oxide)ethyl]amino}-5,8-dihydroxyanthracene-9,10-dione (AQ4N) by P450 2S1 was confirmed, and the NADPH consumption rates were measured aerobically and anaerob...
متن کاملCloning and gene expression of cytochrome P450 gene from Alcanivorax borkumensis Bacterium
Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...

متن کاملCytochrome b5 inhibits electron transfer from NADPH-cytochrome P450 reductase to ferric cytochrome P450 2B4.
Experiments demonstrating that cytochrome (cyt) b5 inhibits the activity of cytochrome P450 2B4 (cyt P450 2B4) at higher concentrations suggested that cyt b5 was occupying the cyt P450 reductase-binding site on cyt P450 2B4 and preventing the reduction of ferric cyt P450 (Zhang, H., Im, S.-C., and Waskell, L. (2007) J. Biol. Chem. 282, 29766-29776). In this work experiments were undertaken with...
متن کاملQuantitative analyses of electrostatic interactions between NADPH-cytochrome P450 reductase and cytochrome P450 enzymes.
A decline in the ionic interactions in the medium with increasing ionic strength (decrease in the ionic activity coefficients) was accompanied by an increase in the fast phase rate constants of CYP2B4 and CYP1A2 reduction. The stimulations were observed both in reconstituted P450 systems and in microsomes. An increase in the ionic strength from 10 to 100 mM sodium phosphate resulted in a 7-fold...
