Bacterial ribosomes stalled on faulty, often truncated, mRNAs lacking stop codons are rescued by trans-translation. It relies on an RNA molecule (tmRNA) capable of replacing the faulty mRNA with its own open reading frame (ORF). Translation of tmRNA ORF results in the tagging of faulty protein for degradation and its release from the ribosome. We used single-particle cryo-electron microscopy to vi
The polymerization of amino acids into proteins occurs on ribosomes, with the rate influenced by the amino acids being polymerized. The imino acid proline is a poor donor and acceptor for peptide-bond formation, such that translational stalling occurs when three or more consecutive prolines (PPP) are encountered by the ribosome. In bacteria, stalling at PPP motifs is rescued by the elongation fact
In the 1930s, a boat-grave was found in Sutton Hoo, England. Soon after, it was noted to have several similarities to swedish boat-grave from the region of Mälardalen, specifically Vendel and Valsgärde. These graves are from the same period as the Sutton Hoo ship burial, in Sweden known as the Vendel period (550-750 AD). Since then there has been an ongoing discussion concerning how the Sutton Hoo
Fotbollen är inte bara en av de mest anrika och populära sporterna världen över, utan även föregångare vad gäller struktur, organisation och kommersialisering. Kanske kan vi därför idag dra lärdom av tidigare skeenden i historien eftersom den har en tendens att upprepa sig själv. Idrottsrörelsen har traditionellt sett hanterat de flesta tvister på egen hand som en del av sin självständighet. Presu

The purpose of this thesis was to examine the EC Commission's role and policy in the EC control of state aid to companies that risk going out of business. The thesis explores the Commission's role in relation to the Member States as well as to the Community courts. It also examines the Commission's policy towards such aid in order to establish whether the Commission is coherent in its

The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2—in particular, its functions in the testis, where Emi2 is expressed at high levels. Male and female Emi2 knockout mice are viable but sterile, in

The Wee1 cell cycle checkpoint kinase prevents premature mitotic entry by inhibiting cyclin-dependent kinases. Chemical inhibitors of Wee1 are currently being tested clinically as targeted anticancer drugs. Wee1 inhibition is thought to be preferentially cytotoxic in p53-defective cancer cells. However, TP53 mutant cancers do not respond consistently to Wee1 inhibitor treatment, indicating the exi

Bacterial ribosomes stall on polyproline stretches and require the elongation factor P (EF-P) to relieve the arrest. Yet it remains unclear why evolution has favored the development of EF-P rather than selecting against the occurrence of polyproline stretches in proteins. We have discovered that only a single polyproline stretch is invariant across all domains of life, namely a proline triplet in
Chatbots are increasingly being adapted as substitutes to humans in customer service. As the level of adoption increases, it becomes more important to understand the phenomenon of robots replacing humans – a new chapter in the rising digital world. Earlier research has explored and aroused criticism against the trend of automation and digitalization, urging companies to move towards a more custome
