title: Interactions between 30s ribosomal proteins and 50s subunits of Escherichia coli.
abstract: The interaction between ribosomal proteins of the 30s subunit with intact 50s subunits was investigated. Experiments with mixtures of total 30s proteins indicated that several 30s proteins including protein s4 would form a stable complex with 50s subunits. Further work with pure s4 indicates that this protein binds stoichiometrically to the 50s subunits, probably through protein-nucleic acid interaction. The possible significance of this interaction is discussed.
