The assembly of prokaryotic ribosomes.
The targets of in vivo studies of the ribosomal assembly process are mainly the events of rRNA processing, whereas in vitro studies (total reconstitution) focus on principles of the assembly process such as assembly-initiation proteins, rate-limiting steps and a detailed sequence of assembly reactions (assembly map). The success of in vitro analyses is particularly remarkable in view of ionic and temperature requirements of the total reconstitution which differ significantly from the in vivo conditions. Features of the in vivo assembly are surveyed, however, the focal point is a description of experimental strategies and results concerning the in vitro assembly of ribosomes.
