Abstract

Przedmiotem wynalazku jest nowa termolabilna nukleaza PPR lub jej enzymatycznie aktywny fragment, wykazujący wysoką aktywność katalityczną w trudnych warunkach reakcyjnych (zwłaszcza wysokie stężenia soli i innych dodatków powszechnie używanych w procesach oczyszczania białek i wirusów, niskie temperatury i pH), gdzie nukleaza ma sekwencję SEQ.2 lub sekwencję, która jest co najmniej w 40% z nią identyczna. Przedmiotem wynalazku są także gen kodujący nukleazę PPR lub jej enzymatycznie aktywny fragment; cząsteczka kwasu nukleinowego kodująca nukleazę PPR lub jej enzymatycznie aktywny fragment; plazmid ekspresyjny zawierający sekwencję genu kodującego PPR; rekombinowany szczep Escherichia coli JM109(DE3) pD454-PPR-AmpR oraz E. coli ArcticExpress (DE3) pD454-PPR-AmpR; sposób wytwarzania białka nukleazy PPR; zastosowanie nukleazy PPR w procesach oczyszczania białek rekombinowanych o znacząco obniżonej zawartości DNA oraz do dekontaminacji odczynników oraz mieszanin reakcyjnych do PCR, qPCR, RT-PCR, RT-qPCR i NGS dla uzyskana zwiększonej czułości i specyficzności odpowiednich analiz genetycznych; zastosowanie nukleazy PPR w procesach oczyszczania białek rekombinowanych, w szczególności enzymów, przeciwciał, antygenów szczepionkowych, przygotowania wektorów wirusowych używanych w terapiach komórkowych, i innych białkach terapeutycznych.
