    Sammanfattning : In order to create a heme environment which permits biomimicry of heme-containing plant peroxidases and investigate the role played by the vinyl side chains of the porphyrin ring on the stability and, possibly, catalytic activity of model compounds, a number of new synthetic microperoxidases -– hemin-6(7)-gly-his methyl ester (HGH) and hemin-6(7)-gly-gly-his methyl ester (HGGH) and hemin-6,7-bis(gly-gly-his methyl ester) (H2GGH) as well as mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH) have been prepared by condensation of a peptide residue with the propionic side chains of hemin, mesohemin and deuterohemin, respectively. Reactivity studies towards different organic and inorganic substrates showed that not only five- but also six-coordinate hemin peptide complexes catalyze the oxidation of substrates by H2O2. LÄS MER

  3. 2. Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants

    Författare :Enrique Terrazas; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Biokemisk teknik; Organic pollutants.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Biochemical technology; Laccase; Lignin peroxidase; Manganese peroxidase; Fusarium sp. strain BOL35; Biodegradation; Bjerkandera sp. strain BOL13; Bioteknik;

    Sammanfattning : This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. LÄS MER

  4. 3. Multifunctional silk: from fabrication to application

    Författare :Manish Singh; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silk; Sonochemistry; Supercritical impregnation; Nanofiller; Soft biosensor; Enzyme mimic;

    Sammanfattning : Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. LÄS MER
