LOCUS       sequence-481872-        6375 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Expression of the engineered N-terminal hybrid-binding domain of 
            RNase H3 (enDR3) for capturing R-loops. A TEV cleavage site, mEGFP 
            and nuclear localization signal (NLS) are included in the fusion..
