Deoxyribonuclease I (Dnase I)
Ibisobanuro
DNase I (Deoxyribonuclease I) ni endodeoxyribonuclease ishobora gusya ADN imwe cyangwa ebyiri.Iremera kandi ikomatanya imiyoboro ya fosifori kugirango itange monodeoxynucleotide cyangwa oligodeoxynucleotide imwe cyangwa ebyiri-ebyiri hamwe na fosifate mumatsinda ya 5'-terminal na hydroxyl kuri 3'-terminal.Igikorwa cya DNase I giterwa na Ca 2+ kandi gishobora gukoreshwa na ion zingana nicyuma nka Mn 2+ na Zn 2+.5 mM Ca 2+ irinda enzyme hydrolysis.Imbere ya Mg 2+, enzyme irashobora kumenya kubushake no gutobora urubuga urwo arirwo rwose rwa ADN.Imbere ya Mn 2+, imirongo ibiri ya ADN irashobora kumenyekana icyarimwe kandi igafatirwa ahantu hamwe kugirango ibe ibice bya ADN bigororotse cyangwa ibice bya ADN bifatanye hamwe na nucleotide 1-2.
