    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tripedalia cystophora; box jellyfish; Cnidaria; Chiropsella bronzie; visual filtering; visual systems; microspectrophotometry; vision; eyes;

    Abstract : Unlike most jellyfish, box jellyfish (cubomedusae) are highly visually orientated. They are agile swimmers and use visual information to avoid obstacles and orientate themselves. READ MORE

    Abstract : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. READ MORE

  5. 3. Structural Insights at Sub-Ångstrom, Medium and Low Resolution: Crystallization of Trypsin, Bacterioferritin, Photosynthetic Reaction Center, and Photosynthetic Core Complex

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein crystallization; cubic phase; sponge phase; bicelle; trypsin; bacterioferritin; reaction center; core complex; photosynthesis;

    Abstract : The catalytic action of serine proteases depends on the interplay of a nucleophile, a general base and a general acid. The catalytic triad is composed of serine, histidine and aspartate residues. The serine acts as a nucleophile while the histidine plays a dual role as the general base or acid at different steps of the reaction. READ MORE
