The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:"
The small ribosomal subunit protein S10 consists of about 100 amino acid residues. In Escherichia coli, S10 is involved in binding tRNA to the ribosome, and also operates as a transcriptional elongation factor.
In phages, S10 participates together with NusB protein (N-utilisation substance B) in processive transcription antitermination. NusE is identical to r-protein S10. In the transcriptionally active NusB-S10 complex, S10 adopts the same fold as in the 30S subunit and is blocked from simultaneous association with the ribosome. The molecular mechanisms by which S10 can act as a translation or a transcription factor are not understood yet.
