Part:BBa_K1084403

promoter3-B0034-RFP-dT

This parts is promoter 3 assembled with mRFP1 expression color generator.

iGEM HokkaidoU Japan 2013 original promoter family is constructed from consensus promoter (BBa_K1084001) by adding mutation at -35 region. Other region is same among family members, and similar with promoter consensus sequence.

t. e. = theoretical transcription efficyency

Promoter transcription efficiency was measured with mRFP1 (BBa_K1084401-K1084410), LacZ and Kanamycine (Km) resistance (BBa_K1084501-K1084505).

Theoretical promoter modeling also has done (see promoter Background page in HokkaidoU 2013 wiki). According to protein, these promoters show relatively another protein activity revel.
