Cytochrome P450 Reductase Structure - Heme, FMN, and Key Residue Y422 #1653453 (License: Personal Use)

This high-resolution molecular visualization depicts cytochrome P450 reductase, a key flavoprotein involved in xenobiotic metabolism. The green and lime ribbons represent α-helices and β-sheets, while the red heme group, blue/gray FMN cofactor, and labeled Y422 residue illustrate critical sites for electron transfer and enzymatic activity. Structural details emphasize conformational dynamics essential for interaction with cytochrome P450 enzymes.

Used in biochemistry, pharmacology, and structural biology educational or research web pages to illustrate enzyme mechanisms, cofactor binding, or mutation studies; matches user intent seeking mechanistic understanding of drug-metabolizing enzymes.
