UniProtKB - P15128 (CP4B1_RABIT)
Protein
Cytochrome P450 4B1
Gene
CYP4B1
Organism
Oryctolagus cuniculus (Rabbit)
Status
Functioni
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.
Catalytic activityi
- an organic molecule + O2 + reduced [NADPH—hemoprotein reductase] = an alcohol + H+ + H2O + oxidized [NADPH—hemoprotein reductase]EC:1.14.14.1
