This interaction presumably causes a conformational change in the actively bound subunit, providing for the efficient release of dTDP from its dTTP binding site. In the process of dTDP release, the ssDNA is transferred to the neighboring subunit, which undergoes a similar process.
This interaction triggers a conformational adjustment in the engaged subunit, allowing for the efficient release of dTDP from its dTTP binding site. This process involves the transfer of ssDNA to an adjacent subunit, which also undergoes a similar structural change.
