    Sammanfattning : The continuous increase in the number and type of Internet services and their requirements for improved QoS has motivated the steady evolution  of cellular networks towards the current fifth generation (5G) systems. However, updating the network to 5G is insufficient to satisfy application requirements since performance limitations can also exist in the transport used by the applications. LÄS MER

  3. 2. Determining the effects of regulatory parameters on the structural dynamics of P-type ATPase membrane transporters

    Författare :Fredrik Orädd; Magnus Andersson; Magnus Wolf-Watz; Marco Cammarata; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; regulation; time-resolved x-ray solution scattering; MD simulation; membrane protein; P-type ATPase; SERCA; CopA; HMA4; adenylate kinase; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Proteins are macromolecular machines with roles in all cellular activities and structures. The functional properties of each protein is the result of its combination of 3D-structure and inherent dynamics, and a wealth of structural and dynamic mechanisms have evolved to regulate protein activity.

  4. 3. CopA and CopT: The Perfect RNA Couple

    Författare :Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []

    Sammanfattning : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. LÄS MER

  7. 5. The Involvement of the structures of antisense RNA, target RNA, and their complexes in plasmid R1 copy number regulation

    Författare :Charlotta Ingvoldstad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Sammanfattning : Plasmid R1 is a low-copy-number plasmid which belongs to the incompatibility group FII. R1 regulates its own copy number. Initiation of replication of plasmid R1 requires the binding of the RepA protein to oriR1. RepA acts in cis and has to be synthesized de novo for each round of replication. LÄS MER
