  1. 1. Computational modelling of enzyme selectivity

    Författare :Paul Bauer; Shina Caroline Lynn Kamerlin; Mikael Widersten; Kenneth Ruud; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enantiomer; epoxide hydrolase; chiral catalysis; empirical valence bond approach; method development; Biokemi; Biochemistry;

    Sammanfattning : Enantioselective reactions are one of the ways to produce pure chiral compounds. Understanding the basis of this selectivity makes it possible to guide enzyme design towards more efficient catalysts. LÄS MER

  2. 2. Diazotrophy and diversity of benthic cyanobacteria in tropical coastal zones

    Författare :Karolina Bauer; Birgitta Bergman; Paul K. Hayes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine cyanobacteria; benthic nitrogen fixation; diversity; diazotrophy; Lyngbya majuscula; Zanzibar; western Indian Ocean; Plant physiology; Växtfysiologi;

    Sammanfattning : Discoveries in recent years have disclosed the importance of marine cyano-bacteria in the context of primary production and global nitrogen cycling. It is hypothesized here that microbial mats in tropical coastal habitats harbour a rich diversity of previously uncharacterized cyanobacteria and that benthic marine nitrogen fixation in coastal zones is substantial.

  3. 3. Utilizing a tectonic framework to constrain the mineral system and remobilization in the Kiruna mining district, Sweden

    Författare :Leslie Logan; Tobias E. Bauer; Fernando Tornos; Olof Martinsson; Paul Evins; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna; tectonic framework; mineral system; IOCG; IOA; remobilization; sulfur isotopes; trace elements; geochronology; Pahtohavare; Viscaria; Rakkurijärvi; Malmgeologi; Ore Geology;

    Sammanfattning : The Kiruna mining district, located in the northern Norrbotten ore province, Sweden, is a geologically and economically important area, being the type-locality for Kiruna iron oxide-apatite (IOA) deposits and also host to a variety of other deposits including syngenetic stratiform exhalative Cu-(Fe-Zn) (Viscaria, Eastern Pahtohavare), epigenetic stratabound Cu ± Au (Pahtohavare), and iron oxide-copper-gold (IOCG, Rakkurijärvi) deposits. However, the timing of IOA versus IOCG within the tectonic evolution is in question based on structural investigations showing Cu- and Fe-sulfides occur in late-orogenic structures. LÄS MER
