FunFam 18: Cytochrome P450 monooxygenase

There are 9 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Cholest-4-en-3-one 26-monooxygenase ((25R)-3-oxocholest-4-en-26-oate forming). [EC: 1.14.15.28]
Cholest-4-en-3-one + 6 reduced [2Fe-2S] ferredoxin + 3 O(2) = (25R)-3- oxocholest-4-en-26-oate + 6 oxidized [2Fe-2S] ferredoxin + 4 H(2)O.
  • This cytochrome P450 (heme-thiolate) enzyme, found in several bacterial pathogens, is involved in degradation of the host cholesterol.
  • It catalyzes the hydroxylation of the C-26 carbon, followed by oxidation of the alcohol to the carboxylic acid via the aldehyde intermediate, initiating the degradation of the alkyl side-chain of cholesterol.
  • The products are exclusively in the (25R) conformation.
  • The enzyme also accepts cholesterol as a substrate.
  • cf. 1.14.15.29.
  • The enzyme can receive electrons from ferredoxin reductase in vitro, its natural electron donor is not known yet.
  • Formerly EC 1.14.13.221.

Biflaviolin synthase. [EC: 1.14.19.69]
(1) 2 flaviolin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+) + O(2) = 3,3'-biflaviolin + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O. (2) 2 flaviolin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+) + O(2) = 3,8'-biflaviolin + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O.
  • This cytochrome-P450 (heme-thiolate) enzyme, from the soil-dwelling bacterium Streptomyces coelicolor A3(2), catalyzes a phenol oxidation C-C coupling reaction, which results in the polymerization of flaviolin to form biflaviolin or triflaviolin without the incorporation of oxygen into the product.
  • The products are highly conjugated pigments that protect the bacterium from the deleterious effects of UV irradiation.
  • Formerly EC 1.14.21.7.

Pimeloyl-[acyl-carrier protein] synthase. [EC: 1.14.14.46]
A long-chain acyl-[acyl-carrier protein] + 2 reduced flavodoxin + 3 O(2) = pimeloyl-[acyl-carrier protein] + an n-alkanal + 2 oxidized flavodoxin + 3 H(2)O.
  • Catalyzes an oxidative C-C bond cleavage of long-chain acyl-[acyl- carrier protein]s of various lengths to generate pimeloyl-[acyl- carrier protein], an intermediate in the biosynthesis of biotin.
  • The preferred substrate of the enzyme from the bacterium Bacillus subtilis is palmitoyl-[acyl-carrier protein] which then gives heptanal as the alkanal.
  • The mechanism is similar to EC 1.14.15.6, followed by a hydroxylation step, which may occur spontaneously.
  • Formerly EC 1.14.15.12.
