How does cycloheximide inhibit translation
WebThis processing event is completely dependent on protein synthesis on mito-ribosomes because it was lost after genetic ablation of mito-ribosomes or by coincubating with chloramphenicol ( Richter et al., 2013 ); the latter blocks translation elongation in the ribosomal A site. WebCycloheximide acts at the large subunit of the ribosome to inhibit translation. Here we report that ubiquitin levels are critical for the survival of Saccharomyces cerevisiae cells in the presence of cycloheximide: ubiquitin overexpression confers resistance to cycloheximide, while a reduced ubiquitin level confers sensitivity.
