Part:BBa_M36998
Coenzyme B-12 Riboswitch for E. coli (nucleotides 1-240)
This part contains the full string of nucleotides for the coenzyme B-12 riboswitch present in Escherichia coli. The aptamer domain of the riboswitch (nucleotides 1-202) undergoes substantial allosteric changes upon binding coenzyme B-12 (aka hydroxocobalamin). The coenzyme B-12 aptamer has one of the most complex metabolite-binding structures of known naturally-occurring riboswitches, though other riboswitches with simpler aptamers can also sense their targets with impressive precision and use resultant structural changes to control gene expression.
Nucleotides 203-240 represent the 5'UTR (untranslated region) upstream of the btuB coding sequence in the E. coli genome.
