Ribosome Binding Sites
A Ribosome Binding Site (RBS) is an RNA sequence found in mRNA to which ribosomes can bind and initiate translation. Translation initiation in bacteria almost always requires both an RBS sequence and a start codon. In the registry, protein coding sequences begin with the start codon. So, if you want to build a BioBrick system that produces a protein, you need to pick an RBS part and put it upstream of the protein coding sequence you want to translate. Note that an RBS is often defined as just that part of the mRNA sequence that binds to the ribosome, however, the surrounding sequence can also affect the translation initiation rate. Consequently, a BioBrick™ RBS part contains the classic RBS but sometimes some surrounding sequence also. See here for a more detailed explanation of how RBSs work.
| Catalog: Are you looking for an RBS to use? The registry has a collection of bacterial and yeast RBSs. We also have a collection of custom RBS sequences useful for some applications. | |
| Design: Are you interested in designing a new RBS or RBS family? Here are some guidelines to help you design and document new RBS. | |
