$A Illustrative diagram of Ribo-seq process used to map the translatome of M. mazei in two growth conditions: Translating ribosomes were initially detected on the mRNAs through the polysome fraction. MNase digestion eliminated unprotected mRNA regions, leading to the transformation of polysomes into monosomes. The translatome in specific experimental conditions was profiled by subjecting 20-34 nucleotide footprints, which were protected and isolated by 70S ribosomes, to cDNA library preparation and deep sequencing. B <t>Fractionation</t> of the cell lysates using sucrose gradients: To avoid the run-off of polysome, cells were harvested during the exponential growth phase using a rapid-chilling method (see Methods). Upon MNase digestion, monosomes were enriched compared to the untreated sample, as indicated by the 70S peak in the green ( + N) and red (-N) profile, contrasting with the Mock black profile.
