Our research:

One of the fundamental processes of life is the translation of mRNA-based information into proteins by the large ribonucleoprotein complex, the ribosome. Traditionally, the ribosome is viewed as a highly conserved machinery with an invariable rRNA and protein complement. Thus, it was not considered to have an intrinsic regulatory capacity, and the efficiency of translation was suggested to be determined either by features inherent to the mRNA or mediated by proteins or RNA regulators. In contrast to this perception, the Moll lab addresses diverse molecular mechanisms of post-transcriptional regulation of gene expression in Bacteria with a special focus on ribosome heterogeneity.
