Purification and characterization of NADPH-cytochrome P450 reductase from Lake Van fish liver microsomes and investigation of some chemical and metals’ effects on the enzyme activity
Purification and characterization of NADPH-cytochrome P450 reductase from Lake Van fish liver microsomes and investigation of some chemical and metals’ effects on the enzyme activity
In addition, optimum ionic strength, optimum pH, optimum temperature, and stable pH values were determined for the enzyme in the kinetic studies performed. K M and Vmax were determined for NADPH and cytochrome c. Effects of some metals ions, antibiotics, and some other drugs used in aquarium fisheries on the activity of the enzyme were investigated. IC50 values and Ki values of metals showing an inhibitory effect were calculated.
