Crystal Structure of MukF(1-287)
Overview
The Escherichia coli MukB, MukE, and MukF proteins form a bacterial condensin (MukBEF) that contributes to chromosome management by compacting DNA. MukB is an ATPase and DNA-binding protein of the SMC superfamily; however, the structure and function of non-SMC components, such as MukF, have been less forthcoming. Here, we report the crystal structure of the N-terminal 287 amino acids of MukF at 2.9 A resolution. This region folds into a winged-helix domain and an extended coiled-coil domain that self-associate to form a stable, doubly domain-swapped dimer. Protein dissection and affinity purification data demonstrate that the region of MukF C-terminal to this fragment binds to MukE and MukB. Our findings, together with sequence analyses, indicate that MukF is a kleisin subunit for E. coli condensin and suggest a means by which it may organize the MukBEF assembly.
