The crystal structure of murine p97/VCP at 3.6A

Overview

p97/VCP is a member of the AAA ATPase family and has roles in both, membrane fusion and ubiquitin dependent protein degradation. Here, we, present a 3.6A crystal structure of murine p97 in which D2 domain has been, modelled as poly-alanine and the remaining approximately 100 residues are, absent. The resulting structure illustrates a head-to-tail packing, arrangement of the two p97 AAA domains in a natural hexameric state with, D1 ADP bound and D2 nucleotide free. The head-to-tail packing arrangement, observed in this structure is in contrast to our previously predicted, tail-to-tail packing model. The linker between the D1 and D2 domains is, partially disordered, suggesting a flexible nature. Normal mode analysis, of the crystal structure suggests anti-correlated motions and distinct, conformational states of the two AAA domains.
