Pore loops of the AAA+ ClpX machine grip substrates to drive translocation and unfolding
Proteolytic AAA+ unfoldases use ATP hydrolysis to power conformational changes that mechanically denature protein substrates and then translocate the polypeptide through a narrow pore into a degradation chamber. We show that a tyrosine in a pore loop of the hexameric ClpX unfoldase links ATP hydroly...
