Structural and functional analysis of the E. coli FtsZ interacting protein, ZapC, reveals insight into molecular properties of a novel Z ring stabilizing protein

ZapC is one of four FtsZ-binding components of the Z ring in bacteria. Formation of the Z ring on the cytoplasmic surface of the membrane is the starting process for assembly of the cell-division apparatus. It binds directly to the Z ring, and although it is not essential for absolute cell division it contributes to it by enhancing the interactions between the FtsZ protofilaments (or polymers) which aggregate to form the ring conformation in the Z ring [1]. This is the C-terminal domain which contains a pocket with a hydrophobic centre surrounded by conserved basic residues, critical for FtsZ binding [2,3].

This entry represents the N-terminal alpha/beta region which contains a pocket, termed the N-domain pocket, lined with residues important for ZapC function as an FtsZ bundler [2,3].
