Identification
HMDB Protein ID HMDBP01547
Secondary Accession Numbers
  • 6843
  • HMDBP05595
  • HMDBP06602
Name Cytochrome P450 1B1
Synonyms
  1. CYPIB1
Gene Name CYP1B1
Protein Type Unknown
Biological Properties
General Function Involved in monooxygenase activity
Specific Function 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. Participates in the metabolism of an as-yet-unknown biologically active molecule that is a participant in eye development.
Pathways
  • Chemical carcinogenesis
  • Metabolism of xenobiotics by cytochrome P450
  • Steroid hormone biosynthesis
  • Tryptophan metabolism
Reactions
RH + reduced flavoprotein + Oxygen → ROH + oxidized flavoprotein + Water details
