Abstract:The ribosome catalyzes oligo/polymerization of amino acids. We designed an allowable modification of amino acid backbone, based on the hypothesized mechanism of peptidyl transfer reaction. Nonsense suppression method was used to investigate the acceptability of these substrates in the prokaryotic ribosomal system. The E.coli ribosome showed a restricted tolerance to the backbone modification, especially for main-chain elongation. However, our designed homologous beta-hydroxyalkanoic acid with elongated methyle… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
