Flexible Nucleic Acids (FNAs) as Informational Molecules: Enzymatic Polymerization of fNTPs on DNA Templates and Nonenzymatic Oligomerization of RNA on FNA Templates

Autor: Maryline, Chemama, Christopher, Switzer

Publikováno v: Methods in molecular biology (Clifton, N.J.). 1973

The methodology enabling enzymatic and nonenzymatic information transfer with FNAs is described. This methodology includes the chemical synthesis of fNTPs and fN phosphoramidites, in addition to protocols for the enzymatic and nonenzymatic transfer o

Aminoacyl-tRNA recognition by the FemXWv transferase for bacterial cell wall synthesis

Autor: Mélanie Etheve-Quelquejeu, Michel Arthur, Ahmed Bouhss, Jean-Marc Valery, Régis Villet, Maryline Chemama, Maxime Lecerf, Matthieu Fonvielle

Publikováno v: Nucleic Acids Research

Transferases of the Fem family catalyse peptide-bond formation by using aminoacyl-tRNAs and peptidoglycan precursors as donor and acceptor substrates, respectively. The specificity of Fem transferases is essential since mis-incorporated amino acids c

International audience; The FemX(Wv) aminoacyl transferase of Weissella viridescens initiates the synthesis of the side chain of peptidoglycan precursors by transferring l-Ala from Ala-tRNA(Ala) to UDP-MurNAc-pentadepsipeptide. FemX(Wv) is an attract

Synthesis of 3'-triazoyl-dinucleotides as precursors of stable Phe-tRNA(Phe) and Leu-tRNA(Leu) analogues

Autor: Mélanie Etheve-Quelquejeu, Emmanuelle Braud, Marco Santarem, Michel Arthur, Jean-Philippe Herbeuval, Nicolas Sakkas, Maryline Chemama, Matthieu Fonvielle, Guillaume Laisné

Publikováno v: Bioorganicmedicinal chemistry letters. 24(15)

We report here the synthesis of stable Phe-tRNA Phe and Leu-tRNA Leu analogues containing a 1,2,3-triazole ring instead of the ribose-amino acid ester bond. The 1,2,3-triazole ring is generated by dipolar cycloaddition of alkyne Phe and Leu analogues

Publikováno v: Organicbiomolecular chemistry. 11(36)

Aminoacyl-tRNAs serve as amino acid donors in many reactions in addition to protein synthesis by the ribosome, including synthesis of the peptidoglycan network in the cell wall of bacterial pathogens. Synthesis of analogs of aminoacylated tRNAs is cr

Publikováno v: Current Protocols in Nucleic Acid Chemistry

Aminoacyl-tRNAs have important roles in a variety of biological processes. Here, we describe the synthesis of stable aminoacyl-tRNA analogs containing 1,4-substituted 1,2,3-triazole rings. The procedure involves (i) copper-catalyzed cycloadditions of
