Metabolism of eicosapentaenoic and docosahexaenoic acids by recombinant human cytochromes P450.
TLDR
It is demonstrated that other polyunsaturated long-chain fatty acids (PUFA-LC), especially the omega3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acids (DHA), are also epoxidised. Expand
Biotic interactions of marine algae.
Marine algae encompass lineages that diverged about one billion years ago. Recent results suggest that they feature natural immunity traits that are conserved, as well as others that appear to beExpand
CYP86A1 from Arabidopsis thaliana encodes a cytochrome P450-dependent fatty acid omega-hydroxylase.
TLDR
Genomic organization analyzed by Southern blot suggested a single gene encoding CYP86A1 in A. thaliana, which was found to catalyze the omega-hydroxylation of saturated and unsaturated fatty acids with chain lengths from C12 to C18 but not of hexadecane. Expand
The Innate Immunity of a Marine Red Alga Involves Oxylipins from Both the Eicosanoid and Octadecanoid Pathways1[w]
TLDR
The dual nature of oxylipin metabolism in this alga suggests that early eukaryotes featured both animal- (eicosanoids) and plant-like (octadecanoids) oxylIPins as essential components of innate immunity mechanisms. Expand
Copper stress induces biosynthesis of octadecanoid and eicosanoid oxygenated derivatives in the brown algal kelp Laminaria digitata.
TLDR
The results suggest that lipid peroxidation participates in the toxic effects of copper and that lipidPeroxidation derivatives may regulate protective mechanisms by employing plant-like octadecanoid signals but also eicosanoid oxylipins which are absent in vascular plants. Expand
Early events in the perception of lipopolysaccharides in the brown alga Laminaria digitata include an oxidative burst and activation of fatty acid oxidation cascades.
This study provides evidence that bacterial lipopolysaccharides can be strong triggers of early events of defence reactions in the brown algal kelp Laminaria digitata, constituting the first reportExpand
CYP94A5, a new cytochrome P450 from Nicotiana tabacum is able to catalyze the oxidation of fatty acids to the omega-alcohol and to the corresponding diacid.
TLDR
A cytochrome P450 able to catalyze the complete set of reactions oxidizing a terminal methyl group to the corresponding carboxyl is described, which is enantioselective: after incubation of a synthetic racemic mixture of 9,10-epoxystearic acid, the chirality of the residual epoxide was 40/60 in favor of 9R,10S enantiomer. Expand
Evidence for oxylipin synthesis and induction of a new polyunsaturated fatty acid hydroxylase activity in Chondrus crispus in response to methyljasmonate.
TLDR
It is demonstrated that methyljasmonate (MeJA) triggers a cascade of oxidation of PUFAs leading to the synthesis of prostaglandins and other oxygenated fatty acids using both oxygenated derivatives of C18 and C20 as developmental or defense hormones. Expand
Cloning, Expression in Yeast, and Functional Characterization of CYP81B1, a Plant Cytochrome P450 That Catalyzes In-chain Hydroxylation of Fatty Acids*
TLDR
A systematic exploration of its function revealed that it specifically catalyzes the hydroxylation of medium chain saturated fatty acids, capric, lauric, and myristic acids. Expand
Functional expression in yeast and characterization of a clofibrate-inducible plant cytochrome P-450 (CYP94A1) involved in cutin monomers synthesis.
TLDR
The chemical tagging of a cytochrome P-450-dependent lauric acid omega-hydroxylase from clofibrate-treated Vicia sativa seedlings with [1-14C]11-dodecynoic acid allowed the isolation of a full-length cDNA designated CYP94A1, which was strong regioselectivity shifted with sulphur-containing substrates.
