  2. 1. Expression of Manganese Lipoxygenase and Site-Directed Mutagenesis of Catalytically Important Amino Acids : Studies on Fatty Acid Dioxygenases

    Author : Mirela Cristea; Ernst H. Oliw; Chao Su; Olof Rådmark; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Dioxygenase; Gaeumannomyces graminis; lipoxygenase; Magnaporthe grisea; oxylipin; Pichia pastoris; hydroperoxide isomerase; polyunsaturated fatty acids; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Abstract : Polyunsaturated fatty acids can be bioactivated by two families of dioxygenases, which either contain non-heme iron (lipoxygenases) or heme (cyclooxygenases, linoleate diol synthases and α-dioxygenases).Lipoxygenases and their products play important roles in the pathophysiology of plants and fungi.

  4. 2. The structural basis for the catalytic specificity of manganese lipoxygenases : 3D structure analysis of the lipoxygenase of Magnaporthe oryzae

    Author : Anneli Wennman; Ernst H. Oliw; Marcia Newcomer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxylipin; lipoxygenase; crystal structure; crystallography; HPLC; mass spectrometry; yeast; site-directed mutagenesis; fungi; Biochemical Pharmacology; Biokemisk farmakologi;

    Abstract : Lipoxygenases (LOX) catalyze regio- and stereospecific oxygenation of polyunsaturated fatty acids to hydroperoxides. These hydroperoxides are further metabolized to leukotrienes and lipoxins in mammals, and are involved in asthma and inflammation. LOX of animals and plants contain iron as catalytic metal (FeLOX).
