'''Crystal Structure of MukF(1-287)'''<br />


==Overview==
==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.
