Rv Dsup codon optimized

contributed by Fudan iGEM 2023

Introduction

Rv Dsup is a damage suppressor protein from the Tardigrade Species Ramazzottius Varieornatus [1] . This is a nucleosome-binding protein that protects chromatin from hydroxyl radicals[2] , thereby inhibiting DNA molecule breakage. This protein can reduce X-ray-induced damage in human cells by 40%.

Usage and Biology

We optimized the codons of wildtype Rv Dsup for ’’E. coli’’ K12 and heterologously expressed it in ’’E. coli’’ to enhance its survival rate under UV radiation.
