Demonstration of erythromycin-dependent stalling of ribosomes on the ermC leader transcript.
ermC encodes a methylase that modifies 23 S rRNA, conferring resistance to macrolide-lincosamide-streptogramin B antibiotics. The expression of this gene is induced by erythromycin using a translational mechanism. We have employed the inherent RNase activity of a Bacillus subtilis S-30 extract as a probe for studying the interaction of ribosomes with ermC mRNA in the presence of antibiotics. 5'...
متن کاملMolecular basis for erythromycin-dependent ribosome stalling during translation of the ErmBL leader peptide.
In bacteria, ribosome stalling during translation of ErmBL leader peptide occurs in the presence of the antibiotic erythromycin and leads to induction of expression of the downstream macrolide resistance methyltransferase ErmB. The lack of structures of drug-dependent stalled ribosome complexes (SRCs) has limited our mechanistic understanding of this regulatory process. Here we present a cryo-e...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
