  1. 6. Functional Models for Non-heme Mononuclear Iron Oxygenases

    Författare :Mainak Mitra; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinorganic chemistry; Iron; Oxygenases; Catalysis;

    Sammanfattning : Non-heme mononuclear iron oxygenases catalyze a large number of oxidation reactions in biological systems. The reactions are often proposed to proceed via the intermediacy of high valent Fe(IV) oxo (ferryl) or, Fe(V) oxo (perferryl) intermediates. LÄS MER

  3. 7. Hydrolytic and oxidative catalytic activities of bio-inspired dinuclear metal complexes

    Författare :Biswanath Das; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinorganic Chemistry; Metalloenzymes; Catalyst; Transition states; Phosphoesterase;

    Sammanfattning : A number of homo- and heterodinuclear complexes have been synthesized as structural and functional models for the the active sites of phosphoesterases and soluble methane monooxygenases. The complexes are based on four new dinucleating ligands containing a central, potentially bridging, phenolate moiety. LÄS MER

  4. 8. Dinuclear metal complexes modelling active sites of metallohydrolases

    Författare :Martin Jarenmark; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinorganic chemistry; enzymes; hydrolases; models; dinuclear; heterodinuclear; phosphotriesterase; purple acid phophatase;

    Sammanfattning : To study the active sites of dinuclear metallohydrolases new metal complexes that model these sites both in structure and function have been synthesized using two new phenol based dinucleating ligands, 2-(N-isopropyl-N-((2-pyridyl)methyl)aminomethyl)-6-(N-(carboxylmethyl)-N-((2-pyridyl)methyl)aminomethyl)-4-methylphenol (IPCPMP) and 2,6-Bis[N-(N-(carboxymethyl)-N-(pyridylmethyl)amine)methyl]-4-methylphenolate (BCPMP). Both ligands contain pyridyl, tertiary amine and carboxylate groups but in IPCPMP one carboxylate donor is exchanged for a non-coordinating group yielding an unsymmetric ligand while BCPMP is symmetric with identical sets of ligands on either side of the phenol group.
