FRAGMENT FROM NATURE features this weekend a chapter called ‘The translation of a sign into another system of signs’ by Korbus Morais, of University of the Free State, South Africa. This article concerns biosemiotics, and is an interesting take on communication in nature. From page 108 in this book. https://lnkd.in/dATmMuTJ View in LinkedIn

FIRST SPACE PROTEIN. “This is the first report of a protein from any extra-terrestrial source. Very high 2H content indicates proto-solar disc or molecular cloud origin. FeO3Fe groups at each end are of a type that could split H2O upon absorption of photons. The existence of a unique chain length suggests that there could be a functionality conferring a replication advantage.” This protein has not been seen on Earth before. https://lnkd.in/d_PBRBQD View in LinkedIn

FEW CRITICAL AMINO ACIDS. “Small changes (e.g., replacement of one amino acid by another) can sometimes cause large changes in structure (this is not always true). Most proteins (particularly the globular proteins) have very similar amino acid composition. A major part of the protein structure acts as a scaffold for the active site. The active site is composed of a relatively few amino acids.” https://lnkd.in/duf9FtUq View in LinkedIn
