A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...
Aminoacyl-tRNA synthetases (aaRSs) are ubiquitous enzymes that provide the critical link between the genetic code and protein biosynthesis. By precisely catalysing the attachment of amino acids to ...
Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...
