Protein Family Models

30S ribosomal protein S10 is involved in the assembly of the 30S ribosomal subunit and the binding of tRNA to the ribosome; it can also function in transcription antitermination

This HMM describes bacterial 30S ribosomal protein S10. In species that have a transcription antitermination complex, or N utilization substance, with NusA, NusB, NusG, and NusE, this ribosomal protein is responsible for NusE activity. Included in the family are one member each from Saccharomyces cerevisiae and Schizosaccharomyces pombe. These proteins lack an N-terminal mitochondrial transit peptide but contain additional sequence C-terminal to the ribosomal S10 protein region.

NusE; involved in assembly of the 30S subunit; in the ribosome, this protein is involved in the binding of tRNA; in Escherichia coli this protein was also found to be involved in transcription antitermination; NusB/S10 heterodimers bind boxA sequences in the leader RNA of rrn operons which is required for antitermination; binding of NusB/S10 to boxA nucleates assembly of the antitermination complex
