Non-ribosomal factors in ribosome subunit assembly are emerging targets for new antibacterial drugs

It is becoming increasingly clear that bacterial ribosome assembly is catalyzed by a variety of non-ribosomal factors. Newly characterized factors in bacterial ribosome biogenesis are broadly conserved and often indispensable proteins that can be classified either as chaperones facilitating assembly, or enzymes with ribosomal RNA- and ribosomal protein-modifying functions. Accumulating evidence indicates that the proteins Era, Obg, YjeQ, YlqF …
