Ribosomal footprints
WebbThe strongest decreases in the rRNA cross-links were observed with pristinamycin IIA and chloramphenicol, which correlates with their both producing complex chemical footprints on 23S rRNA within E. coli ribosomes. Furthermore, gougerotin and pristinamycin IA strongly increased the yields of fragments F2' (U2506) and F4' (U2062/C2063 ... Webb11 apr. 2024 · These mappings, called ribosome footprints, revealed several new ORFs that encoded previously uncharacterized viral protein products. Ribosome profiling can also be used to compare how efficiently different proteins are synthesized.

Webb6 dec. 2024 · Here we use selective ribosome footprinting to analyze the location of ribosomes containing phosphorylated RPS6 on endogenous mRNAs in cells. We find that RPS6 becomes progressively dephosphorylated on ribosomes as they translate an mRNA. Webb4 sep. 2024 · Preparation of Rice Ribosome Footprints. For isolation of ribosome footprints, the RNA concentration of rice polysome extract is first adjusted to 400 ng μL −1, and then 200 μL aliquot is digested with the Illumina TruSeq Ribo Profile Nuclease (0.5 U μg −1 RNA) for approximately 1.4 h in a dry bath (Thermo) that is set at 25°C with …
