Protein splicing is a self-catalysed post-translational process in which an intervening polypeptide segment, known as an intein, excises itself from a precursor protein and ligates the flanking ...

Why do problems occur with a special variant of 'protein glues', the split inteins, that severely limit their use in producing proteins? A team has now answered this question. Proteins are the ...

Proteins are the building blocks of life. They consist of folded peptide chains, which in turn are made up of a series of amino acids. From stabilising cell structure to catalysing chemical reactions, ...
