ribosome binding site


ribosome binding site

The base sequence on a MESSENGER RNA molecule to which a RIBOSOME attaches.

ribosome binding site (RBS)

in prokaryotes, a short NUCLEOTIDE sequence UPSTREAM of a GENE, which, after TRANSCRIPTION, forms the site on mRNA which binds to RIBOSOMES in order to initiate TRANSLATION. The start codon for translation is normally a few nucleotides DOWNSTREAM of the SHINE-DALGARNO SEQUENCE which is within the ribosome binding site.
