  • PMID
  • In certain cases, cytochrome P450 can be fused to its redox partner to produce a bi-functional protein, such as with P450BM-3 from Bacillus megaterium [ PMID: 17023115 ], which has haem and flavin domains. (ebi.ac.uk)
  • enzymology
  • In enzymology, a cytochrome-c3 hydrogenase (EC 1.12.2.1) is an enzyme that catalyzes the chemical reaction 2 H2 + ferricytochrome c3 ⇌ {\displaystyle \rightleftharpoons } 4 H+ + ferrocytochrome c3 Thus, the two substrates of this enzyme are H2 and ferricytochrome c3, whereas its two products are H+ and ferrocytochrome c3.

  • haem
  • Within the second helix is the sequence motif for the c-type cytochromes, CxxCH (residues 21-25), which is covalently attached to the haem through thioether bonds to Cys-21 and Cys-24. (wikipedia.org)
  • residues
  • Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. (wikipedia.org)
  • hydrogen
  • This enzyme belongs to the family of oxidoreductases, specifically those acting on hydrogen as donor with a cytochrome as acceptor. (wikipedia.org)
  • Eight strains of hydrogen bacteria belonging to the genera Hydrogenomonas, Pseudomonas, Nocardia , and to coryneform bacteria have been analyzed with respect to the cytochrome patterns. (springer.com)
  • Nomenclature
  • Comparison of cytochrome P450 (CYP) genes from the mouse and human genomes, including nomenclature recommendations for genes, pseudogenes and alternative-splice variants. (ebi.ac.uk)
  • reactions
  • The p-side quinol deprotonation-oxidation reactions within the cytochrome b6f complex have been implicated in the generation of reactive oxygen species. (wikipedia.org)
