YsxC is an essential P-loop GTPase, that binds to the 50S ribosomal subunit, and is required for the proper assembly of the ribosome. The aim of this study was to characterize YsxC ribosome interactions. The stoichiometry of YsxC ribosome subunit complex was evaluated. We showed that YsxC binding to the 50S ribosomal subunit is not affected by GTP, but in the presence of GDP the stoichiometry of YsxC-ribosome is decreased. YsxC GTPase activity was stimulated upon 50S ribosomal subunit binding. In addition, it is shown for the first time that YsxC binds both 16S and 23S ribosomal RNAs.
