Mechanism of replication-coupled DNA interstrand crosslink repair.

abstract：:FtsK acts at the bacterial division septum to couple chromosome segregation with cell division. We demonstrate that a truncated FtsK derivative, FtsK(50C), uses ATP hydrolysis to translocate along duplex DNA as a multimer in vitro, consistent with FtsK having an in vivo role in pumping DNA through the closing division...

However, neuron-astrocyte coupling of lipid metabolism, particularly in response to neural activity, remains largely uncharacterized.
