  2. 1. Novel Fatty Acid Dioxygenases of Human and Plant Pathogenic Fungi : Studies by Gene Deletion and Expression

    Author : Fredrik Jernerén; Ernst Oliw; Ivo Feussner; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aspergilli; dioxygenase; oxygenase; Magnaporthe oryzae; Gaeumannomyces graminis; Lasiodiplodia theobromae; jasmonic acid; linoleate diol synthase; cyclooxygenase; prostaglandin H synthase; cytochrome P450; oxylipin; hydroperoxide isomerase; allene oxide synthase; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Biochemical Pharmacology; Biokemisk farmakologi;

    Abstract : The dioxygenase-cytochrome P450 fusion proteins (DOX-CYP) comprise a heme-containing enzyme family that shares structural and catalytic properties with mammalian prostaglandin H (PGH) synthases. 7,8-Linoleate diol synthase (7,8-LDS) of Gaeumannomyces graminis was first characterized, and DOX-CYP enzymes are of mechanistic and biological interest.

  4. 2. Jasmonates in root nodule development

    Author : Anna Maria Zdyb; Katharina Pawlowski; Sofie Goormachtig; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lotus japonicus; jasmonic acid; actinorhizal; rhizobia; Frankia; root nodule; lipoxygenase; allene oxide cyclase; allene oxide synthase; Casuarina; Datisca; Medicago; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Jasmonic acid (JA), its derivatives and its precursor form a group of phytohormones, the jasmonates, representing signal molecules involved in plant stress responses, in the defense against pathogens as well as in development. Elevated levels of JA have been shown to play a role in arbuscular mycorrhiza and in the induction of nitrogen-fixing root nodules. READ MORE

  5. 3. Discovery of Novel Fatty Acid Dioxygenases and Cytochromes P450 : Mechanisms of Oxylipin Biosynthesis in Pathogenic Fungi

    Author : Inga Hoffmann; Ernst H Oliw; Alan R Brash; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fusion protein; Linoleate diol synthase; Allene oxide synthase; Cyclooxygenase; Oxygenase; HPLC; Mass spectrometry; Hydroperoxide isomerase; Aspergillus; Fusarium oxysporum; Pharmaceutical Biochemistry; Farmaceutisk biokemi; Farmaceutisk farmakologi; Pharmaceutical Pharmacology; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Dioxygenase-cytochrome P450 (DOX-CYP) fusion enzymes are present in diverse human and plant pathogenic fungi. They oxygenate fatty acids to lipid mediators which have regula­tory functions in fungal development and toxin production. READ MORE
