Ribosomal protein L27 participates in both 50 S subunit assembly and the peptidyl transferase reaction.

Abstract excerpt

Protein L27 has been implicated as a constituent of the peptidyl transferase center of the Escherichia coli 50 S ribosomal subunit by a variety of experimental observations. To define better the functional role of this protein, we constructed a strain in which the rpmA gene, which encodes L27, was replaced by a kanamycin resistance marker. The deletion mutant grows five to six times slower than the wild-type...
