In vitroreconstitution of theEscherichia coli70S ribosome with a full set of recombinant ribosomal proteins

Many studies of the reconstitution of the Escherichia coli small ribosomal subunit from its individual molecular parts have been reported, but contrastingly, similar studies of the large ribosomal subunit have not been well performed to date. Here, we describe protocols for preparing the 33 ribosomal proteins of the E. coli 50S subunit and demonstrate successful reconstitution of a functionally active 50S particle that can perform protein...
