Purification of 70S Ribosomes from Bacillus subtilis
Authors:  Shota Suzuki, Genki Akanuma and Fujio Kawamura, date: 04/05/2015, view: 10295, Q&A: 0
The eubacterial ribosome (70S) is a macromolecular complex that is composed of a small (30S) subunit and a large (50S) subunit. The small subunit comprises the 16S ribosomal RNA (rRNA) and more than 20 ribosomal proteins (r-proteins), whereas the ...
