Description
Parts K613001 through K613006 are T7 promoter variants. K613001 is the T7 promoter wildtype. The other sequences were derived by single base pair mutations that have been shown to alter its strength. The part includes a strong ribosomal binding site. Its strength was determined by cloning it in front of mRFP1 reporter and measuring fluorescence of BL21 cells containing a low copy number plasmid containing the reporter construct.
