<scene name='Celina_Pinto/Sandbox_211/Residues_helical_arch/2'>hydrophobic and positively charged residues</scene> are located. The helical arch is situated in front of the active site and only single-stranded DNA can pass through it. Since the enzyme is able to cleave double-stranded DNA, the enzyme has a conformational flexibility to facilitate DNA threading which is required to process the 5' nuclease substrates in the active site. | <scene name='Celina_Pinto/Sandbox_211/Residues_helical_arch/2'>hydrophobic and positively charged residues</scene> are located.
