Protein originally found in Streptococcus thermophilius where it regulates natural competence. The protein activation and binding to specific promoters (ComR Box; BBa_K2341001) is only possible in presence of a short peptide, ComS (LPYFAGCL). Binding to the promoter will induce the downstream sequence expression.
Promote expression of the sequence downstream in presence of ComR (BBa_K2341000) and ComS (LPYFAGCL). Sequence containing the palindrome motif needed to bind ComR (= ComR box).
RNA guide to use in combination with CRISPR/CAS9. Cut inside the tyrA gene so that deletion by homologous recombination can occur if a homologous DNA strand is also added. RNA guide under constitutive expression by BBa_J23119.
The pBAD promoter is a very common inducible one that is activated by L-arabinose and repressed by araC.
Terminators are necessary to stop the transcription at the end of a coding sequence.
