Disease relevance of CPD


High impact information on CPD


Chemical compound and disease context of CPD


Biological context of CPD


Anatomical context of CPD

  • Heterologous expression of CYP73A5, an Arabidopsis cytochrome P450 monooxygenase, in baculovirus-infected insect cells yields correctly configured P450 detectable by reduced CO spectral analysis in microsomes and cell lysates [13].

Associations of CPD with chemical compounds

  • Our results imply that the ROT3 protein is a member of a new class of cytochrome P-450 encoding putative steroid hydroxylases, which is required for the regulated polar elongation of cells in leaves of Arabidopsis [6].
  • Brassinosteroids (BRs) are biosynthesized from campesterol via several cytochrome P450 (P450)-catalyzed oxidative reactions [14].
  • The basis for the mutant phenotype is the enhanced expression of a cytochrome P450 (CYP72B1). bas1-D suppresses a phyB-null allele, but not a phyA-null mutation, and partially suppresses a cryptochrome-null mutation [15].
  • Selective interaction of triazole derivatives with DWF4, a cytochrome P450 monooxygenase of the brassinosteroid biosynthetic pathway, correlates with brassinosteroid deficiency in planta [16].
  • Repression of CPD transcription by brassinosteroids is sensitive to the protein synthesis inhibitor cycloheximide, indicating a requirement for de novo synthesis of a regulatory factor [17].
