Deoxyribonuclease I (Dnase I)
Tsanangudzo
DNase I (Deoxyribonuclease I) inonzi endodeoxyribonuclease inokwanisa kugaya DNA imwe kana ine tambo mbiri.Inoziva uye inotsemura mabhondi ephosphodiester kugadzira monodeoxynucleotides kana oligodeoxynucleotides imwe kana kaviri-yakasungwa nemapoka ephosphate pa5'-terminal uye hydroxyl pa3'-terminal.Chiitiko cheDNase I chinoenderana neCa 2+ uye chinogona kuitwa ne divalent metal ions seMn 2+ uye Zn 2+.5 mM Ca 2+ inodzivirira iyo enzyme kubva kuhydrolysis.Pamberi peMg 2+, enzyme yaigona kuona nekutsemura chero nzvimbo pane chero tambo yeDNA.Pamberi peMn 2+, tambo mbiri dzeDNA dzinogona kuzivikanwa panguva imwe chete uye dzakatsemurwa panzvimbo inenge imwe chete kuti iite zvimedu zveDNA zvakati sandara kana kuti zvimedu zveDNA zvinonamira zvine 1-2 nucleotides.
