title: Ribosomal proteins, TL4 and TL5, from Thermus thermophilus form hybrid complexes with 5 S ribosomal RNA from different microorganisms.
abstract: Hybrid complexes of the ribosomal proteins, TL4 and TL5, from Thermus thermophilus with 5 S ribosomal RNA from Escherichia coli and Bacillus stearothermophilus have been prepared. There was no competition between the two proteins for the binding sites. Stoichiometry of 5 S RNA binding for both proteins was 1:1 (protein/RNA). The TL4 protein competed with the E. coli ribosomal L5 protein, and the TL5 protein competed with the E. coli ribosomal proteins, L18 and L25, for binding with 5 S RNA.
