New research suggests that ocean turbulence and horizontal stirring will dramatically increase in the Arctic and Southern Oceans due to human-induced Global Warming. The study uses ultra-high-resolution simulations to investigate how mesoscale horizontal stirring (MHS) responds to warming, revealing a pronounced future intensification ...
Researchers have elucidated the molecular mechanism of selenocysteine insertion into proteins, revealing a complex interaction between ribosomes and mRNA signaling sequences. This discovery has important implications for understanding human health and disease, particularly in relation to cancer prevention and thyroid function.
Selenocysteine is an essential amino acid for certain species, including humans and vertebrates, while others have lost it. Researchers from the Centre for Genomic Regulation have discovered that nine out of 1,000 fungi genomes contain selenocysteine.
Researchers at MIT have developed a novel chemical synthesis method that can modify antibiotics, making them more effective against drug-resistant infections. The technique uses an amino acid called selenocysteine as a 'handle' to link peptides and small-molecule drugs.
Selenium's incorporation into selenoproteins requires a unique elongation factor called eEFSec that helps recognize the stop codon as coding for selenocysteine. The discovery sheds light on how selenium is handled differently during protein synthesis due to its high reactivity.
Scientists discovered that microorganisms recognize multiple codons for the rare amino acid selenocysteine, expanding our understanding of the genetic vocabulary. The findings also highlight the context-dependency of the genetic code and its potential plasticity.
Researchers at TUM elucidated the structure of PylB, an enzyme crucial for pyrrolysine biosynthesis. The discovery sheds light on how archaebacteria modify existing systems to create tailored amino acids with unique properties.
Researchers at Yale University detail the molecular mechanisms governing selenium metabolism in the human body. The study reveals a highly specialized tRNA molecule responsible for selenocysteine production, which is crucial for recycling protective antioxidants.
