Ko te topology membrane o te rohe hongere colicin E1 i akohia e te whakawhiti hiko resonance resonance (FRET).I whai waahi te FRET ki te waikawa amino rekoata (coumarin) kua whakawaeherehia ira hei kaituku me te toenga o te cysteine ​​kua tohua ki te DABMI (4-(dimethylamino)phenylazophenyl-4'-maleimide) hei kaiwhiwhi FRET.Ko te toenga o te coumarin fluorescent i whakauruhia ki roto i te pūmua ma te orthogonal tRNA/aminoacyl-tRNA synthetase takirua e taea ai te whakauru whiriwhiri ki tetahi waahi i roto i te rohe hongere colicin.Ko ia momo rereke ka mau i te rerekee (TAG) mo te kaporeihana coumarin me te huringa cysteine ​​(TGT) mo te taapiri DABMI.E ono nga tawhiti i roto i nga helices 1-6 i whakatauhia ma te whakamahi i te tātaritanga FRET mo nga ahuatanga whakarewa me te herea-meira.Ko nga raraunga FRET i whakaatu i nga huringa nui i roto i nga tawhiti interhelical i waenga i nga helices 3-6 i runga i te hononga membrane e whakarato ana i te matauranga hou ki te hanganga here-membrane o te rohe hongere.I te nuinga o te waa, ka heke te kaha o te coumarin-DABMI FRET i runga i te here o te membrane, ka hanga ki runga i te tauira marara mo te hongere colicin.I whakawhanakehia he tauira mo te katinga o te rohe hongere i runga i nga raraunga FRET o naianei me te whakaputa i mua.Ko te tauira e whakaatu ana i te whakatakotoranga porohita o nga helices 1-7 i roto i te anga karaka mai i te taha extracellular me te hononga atanga membrane o nga helices 1, 6, 7, me te 10 huri noa i te makawe transmembrane pokapū i hangaia e nga helices 8 me 9.
