Ribosome-binding factor A [PubMed9422595] (gene rbfA) is a bacterial protein that associates with free 30S ribosomal subunits. It does not associate with 30S subunits that are part of 70S ribosomes or polysomes. It is essential for efficient processing of 16S rRNA. Ribosome-binding factor A is a protein of from 13 to 15 Kd which is found in most prokaryotic organisms. A putative chloroplastic form seems to exist in plants.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 6 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a Ribosome-binding factor A, RbfA domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 6 hidden Markov models representing the Ribosome-binding factor A, RbfA superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
