This entry represents the C-terminal Ribonuclease H-like domain in the terminase (large subunit) from Escherichia phage T7 (Bacteriophage T7) [1]. The terminase functions as an ATP-powered molecular motor essential for the translocation of viral DNA into empty capsids. It also acts as an endonuclease, cleaving the viral genome at a specific and precise double-stranded DNA sequence to initiate and conclude the packaging process.	Domain
