Dataset Summary
TitleIdentification of MukBHN conformational changes upon AcpP binding using cross-linking mass spectrometry
DescriptionStructural Maintenance of Chromosomes (SMC) complexes contribute ubiquitously to chromosome organization-segregation. SMC proteins have a conserved architecture, with a dimerization hinge and an ATPase head domain separated by a long antiparallel intramolecular coiled-coil. Dimeric SMC proteins interact with essential accessory proteins, kleisins that bridge the two subunits of an SMC dimer, and HAWK/KITE accessory proteins that interact with kleisins. The ATPase activity of the Escherichia coli SMC protein, MukB, is essential for in vivo function and is regulated by interactions with its dimeric kleisin, MukF, and KITE, MukE. Here we demonstrate that, in addition, MukB interacts with Acyl Carrier Protein (AcpP) that has essential functions in fatty acid synthesis. We characterize the AcpP interaction site at the joint of the MukB coiled-coil and show that the interaction is essential for MukB ATPase and for MukBEF function in vivo. Therefore, AcpP is an essential co-factor for MukBEF action in chromosome organization-segregation.
