Ribosome-binding factor A signature
Ribosome-binding factor A  (gene rbfA) is a bacterial protein that
associates with free 30S ribosomal subunits. It does not associates 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
As a signature pattern, we selected the best conserved region which is located
in the second half of the protein.
