Crystal structure of arp2/3 complex

WebMar 26, 2007 · We determined crystal structures of bovine Arp2/3 complex cocrystallized with various bound adenine nucleotides and cations. Nucleotide binding favors closure of the nucleotide-binding cleft of Arp3, but no large-scale conformational changes in the complex. Thus, ATP binding does not directly activate Arp2/3 complex but is part of a network of ... WebSep 20, 2011 · 3D reconstructions of Arp2/3 complexes bound to different NPFs.
