Rv Dsup codon optimized
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.
