Structure and dynamics of bacterial ribosome biogenesis

Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit (which contains the 18S rRNA and 33 ribosomal proteins). The ribosomal proteins are encoded by ribosomal genes. WebRibosome biogenesis is a major cellular process in all living cells and is tightly connected to the cell cycle and its regulation. Even minor changes in this pathway can result in ribosomopathies and can also lead to severe diseases including cancer. However, targeted ribosome biogenesis is an emerging therapeutic method for cancer cure.
