  2. 1. Classes of DNA associated with telomeres in the chironomids C. pallidivittatus and C. tentans

    Author : Iréne Kamnert; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; Chironomus; subtelomere; gene conversion; subfamilies; telomere; complex repeats; cytogenetics; Genetik; cytogenetik;

    Abstract : Telomeres in Chironomus consist of long complex tandem DNA repeats, which in C. pallidivittatus have been shown to extend to the extreme end of chromosomes. In C. pallidivittatus the telomeric repeats are present in large blocks, 50-200kb in size, most of them belonging to four major subfamilies. READ MORE

  4. 2. Three Subfamilies of KRAB Zinc Finger Proteins : A Structural, Functional and Evolutionary Analysis

    Author : Charlotta Mark; Lars Hellman; Fredrik Öberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Krüppel zinc finger; KRAB; TIF1β; transcriptional repression; Biologi; Biology; Biologi; Molecular Immunology; molekylär immunologi;

    Abstract : Krüppel-related zinc finger proteins constitute the largest single class of transcription factors within the human genome. Members of this protein family have the ability to either activate or repress transcription depending on the presence of specific activator or repressor domains within the protein. READ MORE

  5. 3. Cytochrome P450 Enzymes in Bile Acid Biosynthesis and Fatty Acid Metabolism : Studies on Members of the Porcine CYP4A and CYP8B Subfamilies

    Author : Kerstin Lundell; Kjell Wikvall; Ronnie Hansson; Stefan Alexson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; cytochrome P450; bile acids; fatty acids; CYP4A; CYP8B; genome; porcine; hyocholic acid; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi; farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : The present investigation is devoted to studies on porcine members of the cytochrome P450 4A (CYP4A) and CYP8B1 subfamilies, which are involved in bile acid biosynthesis and fatty acid metabolism. Hyocholic acid is considered to fulfil the requirements for trihydroxy bile acids in the domestic pig (Sus scrofa) in the absence of cholic acid. READ MORE

  6. 4. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Author : Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
    Keywords : GH5; glycoside hydrolase; subfamily classification; mannans; polysaccharides; mannanases; cell wall; GH5; glykosidhydrolas; subfamiljklassificering; mannaner; polysackarider; mannanaser; cellvägg; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. READ MORE

  7. 5. Prediction of function shift in protein families

    Author : Saraswathi Abhiman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Protein function; Divergence; Function shift; Subfamily;

    Abstract : With the availability of a large number of complete genome sequences, it has become essential to annotate the protein sequences derived from them as precisely as possible. Even though presently available computational methods can predict broad functionality for most protein sequences, there is room for improvement in order to get more precise functional annotation.
