Qaab dhismeedka 3D ee la saadaalin karo ee DNA-da laba-geesoodka ah ayaa ka dhigaya mid ku habboon qaab-dhismeedka qaabaynta hoose ee goobaha firfircoon ee ku salaysan nucleic acid.Waxaan halkan ku baadhaynaa isticmaalka 14mer DNA duplex si ay u noqoto meelaynta saxda ah ee la saadaalin karo ee hawlaha catalytic.Marka la eego ka qaybgalka guud ee kooxda imidazole ee ku salaysan histidine ee aqoonsiga borotiinka iyo dhacdooyinka catalysis, hal histidine-la mid ah duplexes wax laga beddelay ayaa la baaray.Ku xidhidhista histamine ee C5 ee saldhiga taymiinka iyada oo loo sii marayo curaarta amide, waxay ogolaataa meelaynta dabacsan ee shaqada imidazole ee jeexdin weyn.Isdhexgalka wadajirka ah ee ka dhexeeya imidazole iyo duplex iyo saamaynta ay ku leedahay imidazolium pKaH waxaa lagu baarayaa iyada oo la gelinayo hal tamiin oo la beddelay afar meelood oo kala duwan oo ku yaal bartamaha 14mer helix double.Isticmaalka NMR iyo dhaqdhaqaaqyada molecular ee aan la xakameynin, qaab dhismeed ku lug leh samaynta curaarta hydrogen ee u dhaxaysa imidazole iyo Hoogste ee dhinaca saldhigyada guanine ee labada lamaane ee GC ee deriska ah ayaa la aasaasay.Ujeedadu waxay ka qayb qaadanaysaa xasilinta ka dhanka ah dhalaalka kulaylka ee 6°C waana furaha habaynta pKaH ee kooxda imidazolium.Tilmaamaha guud, shuruudaha iyo dabeecadda guud ee hindise-sharciyeedka cusub ee pKaH ayaa lagu sifeeyay.
