title: Functional study of the residue C899 in the 900 tetraloop of Escherichia coli small subunit ribosomal RNA.
abstract: A mutant ribosome bearing C899G in the 900 tetraloop of Escherichia coli 16S rRNA, one implicated in a conformational switch in the dynamic movements of the ribosome, showed defects in subunit association and 30S initiation complex formation. Our results explain the basis of the loss of protein synthesis ability caused by a perturbation of the 900 tetraloop.
