  1. 16. The structure of phenol hydroxylase and its relation to other flavoenzymes

    Författare :Cristofer Enroth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The NADPH-dependent flavin monooxygenase phenol hydroxylase catalyses the first step in the microbial degradation pathway of phenol and several phenol derivatives. It catalyses the introduction of a hydroxyl group in the ortho-position on the aromatic ring. LÄS MER

  2. 17. Genes encoding homeodomain-leucine zipper proteins in Arabidopsis thaliana

    Författare :Eva Söderman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi;

    Sammanfattning : A new class of transcription factors, the homeodomain-leucine zipper (HD-Zip) proteins,have been identified in Arabidopsis thaliana. These proteins contain a homeodomainfollowed by a leucine-zipper motif, a combination so far only found in plants. LÄS MER

  3. 18. Site and Mechanism of Action of Resin Acids on Voltage-Gated Ion Channels

    Författare :Malin Silverå Ejneby; Fredrik Elinder; Johan Brask; Dirk Snyders; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Voltage-gated ion channels are pore-forming membrane proteins that open or close their gates when the voltage across the membrane is changed. They underlie the electrical activity that enables the heart to pump blood and the brain to receive and send signals. LÄS MER

  4. 19. Multiple regulatory inputs for hierarchical control of phenol catabolism by Pseudomonas putida

    Författare :W. K. Anjana Madhushani; Victoria Shingler; Livia Leoni; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P. putida; Phenol catabolism; dmpR; dmp-System; 5’-LR; Carbon Catabolite Repression; Transcriptional Translational regulation; Crc; CrcZ; CrcY; Hfq;

    Sammanfattning : Metabolically versatile bacteria have evolved diverse strategies to adapt to different environmental niches and respond to fluctuating physico-chemical parameters. In order to survive in soil and water habitats, they employ specific and global regulatory circuits to integrate external and internal signals to counteract stress and optimise their energy status.

  5. 20. Computer simulations of ribosome reactions

    Författare :Stefan Trobro; Johan Åqvist; Arieh Warshel; Uppsala universitet; []
    Nyckelord :Molecular biology; ribosomal termination; Empirical valence bond; peptidyl transfer; Molekylärbiologi;

    Sammanfattning : Peptide bond formation and translational termination on the ribosome have been simulated by molecular mechanics, free energy perturbation, empirical valence bond (MD/FEP/EVB) and automated docking methods. Recent X-ray crystallographic data is used here to calculate the entire free energy surface for the system complete with substrates, ribosomal groups, solvent molecules and ions. LÄS MER
