Structural Enzymology, Phylogenetics, Differentiation, and Symbolic Reflexivity at the Dawn of Biology

Guo Qing Tang, Charles W Carter, Milena Popović, Mark Adam Ditzler et autres

Translation of symbols in one chemical language into another defined genetics. Yet, the co-linearity of codons and amino acids is so commonplace an idea that few even ask how it arose. Readout is done by two distinct sets of proteins, called aminoacyl-tRNA …

Coevolution of RNase P and the ribosome

Anton S. Petrov, Claudia Álvarez-Carreño, Loren Dean Williams, Mark Adam Ditzler

Translation is carried out by the most conserved assemblies in biology. Among these assemblies, the ribosome and RNase P are central players. These ancient ribonucleoprotein complexes achieved structural and functional maturity by the last universal common ancestor (LUCA) of life. In prior …

Abstract 1872 In vitro selection of noncovalent assemblies to inform the search for the first ribozymes

Zachary Cohen, Maxwell H. Packebush, Milena Popović, Mark Adam Ditzler

In vitro selection simulates natural evolutionary processes, including the optimization of enzymes and ribozymes during the emergence of life. Typically, in vitro selection experiments identify individual oligomers with important functions. However, noncovalent interactions between oligomers (e.g. polypeptide subunits of a multimeric polymerase) …

PURE mRNA display and cDNA display provide rapid detection of core epitope motif via high‐throughput sequencing

Sabrina Galiñanes Reyes, Yutetsu Kuruma, Mai Fujimi, Masako Yamazaki et autres

Abstract The reconstructed in vitro translation system known as the PURE system has been used in a variety of cell‐free experiments such as the expression of native and de novo proteins as well as various display methods to select for functional polypeptides. …
