Bu çalışmada, gökkuşağı alabalığı karaciğerinden saflaştırılan mitokondrial tiyoredoksin redüktaz enzimi aktivitesi üzerine bazı herbisit ve insektisitlerin in vitro etkileri incelendi. Enzimin saflaştırılmasında 2’, 5’­ADP Sepharose 4B afinite kromatografisi yöntemi kullanıldı. Enzim 11,8 EÜ/mg protein spesifik aktiviteyle, % 2,38 verimle ve 648,4 kat saflaştırıldı. Enzimin saflık kontrolü Sodyum Dodesil Sülfat-Poliakrilamid Jel Elektroforezi (SDS-PAGE) ile yapıldı ve tüm kinetik çalışmalarda saf enzim kullanıldı. Yapılan kinetik çalış­malarda 4’ü herbisit 4’ü insektisit olmak üzere kullanılan tüm pestisitlerin enzim üzerinde inhibisyon etkisi tespit edildi.
