Domain relationships



This entry represents the ZipA C-terminal domain. ZipA, a membrane-anchored protein, is an essential cell division protein involved in septum formation [PMID: 9008158, PMID: 9864327]. FtsA and the C-terminal domain of ZipA bind FtsZ, a homologue of eukaryotic tubulins and a major component of the bacterial septal ring [PMID: 10209756], at the prospective division site. This is followed by the sequential addition of FtsK, FtsQ, FtsL, FtsW, FtsI, and FtsN [PMID: 11163134,PMID: 11948172,PMID: 11847116]. ZipA contains three domains: a short N-terminal membrane-anchored domain, a central P/Q domain that is rich in proline and glutamine and a C-terminal domain, which comprises almost half the protein. The structure of the C-terminal domain is an alpha-beta fold with three alpha helices and a beta sheet of six antiparallel beta strands. The major loops protruding from the beta sheet surface are thought to form a binding site for FtsZ [PMID: 10924108].
