Deciphering a biochemical mechanism explains the center of protein factories

Based on genetic blueprints, individual amino acids are assembled into long amino acid chains, the proteins, in the protein factories of our cells, the ribosomes. Each newly formed protein starts with the amino acid methionine.

Exploring metabolic compatibility as a possible limiting factor to prokayrotic endosymbioses

"One of the great mysteries of biology," says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, "is eukaryogenesis, or how eukaryotes arose." Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.

Study reveals a previously unknown mechanism for DNA folding

A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics.

Is mRNA decoding in humans structurally and kinetically distinct from bacteria?

Researchers examined molecular-level differences in ribosomal translational fidelity between humans and bacteria.

Researchers identify the mSWI/SNF chromatin remodeling complex as a host-directed drug target for SARS-CoV-2 infection

Researchers showed that mammalian SWItch/Sucrose Non-Fermentable (mSWI/SNF) chromatin remodeling complexes represent a potential class of host-directed broad-acting SARS-CoV-2 therapeutic targets.

Study finds a new mammalian antiviral response pathway restricting poxviruses replication

In a recent study posted to the bioRxiv* preprint server, researchers identified a novel antiviral pathway different from the interferon (IFN) pathway that inhibited poxvirus(es) replication.

Molecular switch regulates autophagy in plants

Autophagy, or "self-eating", is an essential cellular quality control mechanism that clears the cell of protein aggregates and damaged organelles. This mechanism is inactive under normal conditions and only triggered upon persistent cellular stress.

Transcriptomics analysis identifies thousands of viroid-like circular RNA molecules

Metatranscriptomics analysis reveals the existence of over ten thousand viroids and viroid-like RNAs.

Researchers explore the mechanism involved in the living world’s fastest cell movements

Raphidocystis contractilis belongs to Heliozoa, a group of eukaryotes commonly found in fresh, brackish, and sea water.

Researchers identify inhibitors of the SARS-CoV-2 Nsp14 N7-methyltransferase

A recent study identified inhibitors for SARS-CoV-2 non-structural protein 14 (Nsp14).

The loss of epigenetic information accelerates the aging process

A new study in the journal Cell aimed to determine whether epigenetic changes are a cause of mammalian aging.

Study offers novel insights into the elongation dynamics of eukaryotic cells

Life depends on the precise functioning of several proteins synthesized in cells by ribosomes. This diverse set of proteins, known as a proteome, is maintained by the robust translation elongation of amino acid sequences taking place in the ribosomes.
