Nucleotide-dependent DNA gripping and an end-clamp mechanism regulate the bacteriophage T4 viral packaging motor
Packaging of viral DNA depends on strong molecular motors that are powered by ATP hydrolysis. Here, the authors develop a single-molecule assay to monitor how nucleotide binding regulates motor-DNA interactions and reveal a generic mechanism that prevents exit of the whole DNA from the viral capsid...

| Sumario: | Packaging of viral DNA depends on strong molecular motors that are powered by ATP hydrolysis. Here, the authors develop a single-molecule assay to monitor how nucleotide binding regulates motor-DNA interactions and reveal a generic mechanism that prevents exit of the whole DNA from the viral capsid during packaging. |
