  2. 1. SYSBIOMICS of Aspergilli: SYStems Biology, BIoinformatics and OMICS analysis of Aspergilli cell factories

    Author : Wanwipa Vongsangnak; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Biology; Aspergilli; Bioinformatics; Omics analysis;

    Abstract : Aspergilli represent a group of filamentous fungi that plays a key role in industrialbiotechnology, and as human, animal and plant pathogens. Here three Aspergillus species,namely Aspergillus oryzae, Aspergillus niger and Aspergillus nidulans are considered. READ MORE

  4. 2. Catalytic and Structural Properties of Heme-containing Fatty Acid Dioxygenases : Similarities of Fungal Dioxygenases and Cyclooxygenases

    Author : Ulrike Garscha; Ernst Oliw; Per-Johan Jakobsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dioxygenase; prostaglandin H synthase; Gaeumannomyces graminis; Aspergilli; hydroperoxide isomerase; linoleate diol synthase; cytochrome P450; oxylipin; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : 7,8-Linoleate diol synthase (7,8-LDS) of the take-all pathogen of wheat, Gaeumannomyces graminis, converts linoleic acid to 8R-hydroperoxyoctadecadienoic acid (8-HPODE) by 8-dioxygenase activity (8-DOX), and further isomerizes the hydroperoxide to 7S,8S-dihydroxyoctadecadienoic acid (7,8-DiHODE) by hydroperoxide isomerase activity. Sequence alignment showed homology to prostaglandin H synthase (PGHS), and both enzymes share structural and catalytic properties. READ MORE

  5. 3. 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.

  6. 4. Malic acid production by Aspergillus oryzae

    Author : Christoph Knuf; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C4 dicarboxylic acids; Aspergillus oryzae; systems biology; fermentation; malic acid; metabolic engineering;

    Abstract : Malic acid is a C4 dicarboxylic acid which is used as an acidulant in food and beverages. It isalso considered as a bio-building block to replace petrochemically derived compounds in thepost oil era. This organic acid can be biotechnologically derived from fermentation usingrenewable feedstocks as carbon source. READ MORE

  7. 5. Trehalose metabolism and stress resistance in Aspergillus niger

    Author : Åsa Svanström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Food spoilage by filamentous fungi, moulds, is a global issue of great significance. Mould growth can cause food losses due to deterioration, and adverse health effects due to toxin production. Conidia, asexual spores, are the main factors of dispersal and infection in most food-relevant moulds. READ MORE
