FunFam 111999: L-ornithine N5-oxygenase SidA

There are 1 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
L-ornithine N(5)-monooxygenase (NAD(P)H). [EC: 1.14.13.196]
L-ornithine + NAD(P)H + O(2) = N(5)-hydroxy-L-ornithine + NAD(P)(+) + H(2)O.
  • The enzyme from the pathogenic fungus Aspergillus fumigatus catalyzes a step in the biosynthesis of the siderophores triacetylfusarinine and desferriferricrocin, while the enzyme from the bacterium Kutzneria sp. 744 is involved in the biosynthesis of piperazate, a building block of the kutzneride family of antifungal antibiotics.
  • Activity of the fungal enzyme is higher with NADPH, due to the fact that following the reduction of the flavin, NADP(+) (but not NAD(+)) stabilizes the C4a-hydroperoxyflavin intermediate that oxidizes the substrate.
  • Cf. EC 1.14.13.195.
