Bifunctional cytochrome P450/NADPH--P450 reductase

Gene

CYP505

Organism
Fusarium oxysporum (Fusarium vascular wilt)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Functions as a fatty acid monooxygenase (PubMed:8830036, PubMed:11985584). Catalyzes hydroxylation of fatty acids at omega-1, omega-2 and omega-3 positions (PubMed:11985584). Shows activity toward fatty acids with a chain length of 9-18 carbons with optimum chain lengths of 12-14 carbons (lauric, tridecylic and myristic acids) (PubMed:8830036, PubMed:11985584). Can also use shorter saturated fatty acids with a chain length of 9 or 10 carbons as substrates (PubMed:11985584). Also displays a NADPH-dependent reductase activity in the C-terminal domain, which allows electron transfer from NADPH to the heme iron of the cytochrome P450 N-terminal domain (PubMed:8830036, PubMed:11985584).2 Publications

Catalytic activityi

RH + [reduced NADPH--hemoprotein reductase] + O2 = ROH + [oxidized NADPH--hemoprotein reductase] + H2O.2 Publications
NADPH + n oxidized hemoprotein = NADP+ + n reduced hemoprotein.2 Publications

Cofactori

Protein has several cofactor binding sites:

Enzyme regulationi

Stimulated NADPH--cytochrome reductase activity in the presence of substrate. Inhibited by fatty acid substrates longer than 13 carbons and the degree of inhibition increases with increasing chain length.1 Publication

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
