Webb28 mars 2024 · Ribosomes are the roundish structures upon which the amino acids of a protein are strung together, following the instructions of a gene’s DNA sequence. A ribosome is a conglomeration of RNA molecules as well as proteins. The rDNA of the new clock encodes those ribosomal proteins. WebbAs with macrolides, solithromycin works by binding to the 50S ribosomal subunit near the peptide exit tunnel, resulting in premature termination of translation and frame shift errors in translation. 29 This mechanism is usually considered bacteriostatic, but ketolides are considered bactericidal, possibly due to their added ability to interfere with formation of …
