    Sammanfattning : Synthesis of proteins is performed by the ribosome, a large ribonucleoprotein complex. Apart from the ribosome, numerous protein factors participate in this process. Elongation factor 2 (eEF2) is one of these factors. eEF2 is an essential protein with a mol. LÄS MER

  4. 4. The ribosome, stringent factor and the bacterial stringent response

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Rose-Marie Jenvert; Stockholms universitet.; Södertörns högskola.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi; cellbiologi; Cellbiology; Ribosome; stringent factor; stringent response; tRNA; ribosomal protein L11; pppGpp;

    Sammanfattning : The stringent response plays a significant role in the survival of bacteria during different environmental conditions. It is activated by the binding of stringent factor (SF) to stalled ribosomes that have an unacylated tRNA in the ribosomal A-site which leads to the synthesis of (p)ppGpp. LÄS MER

  5. 5. Cell Behavior and the Role of Profilin

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Yu Li; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. LÄS MER
