摘要：

FtsZ is the key protein in cell division in bacteria. We have proposed that lipid domains in the cytoplasmic membrane play a role in the localisation of FtsZ. In order to test this hypothesis, we used a model system based on Langmuir films to simulate the bacterial membrane. In this simple system we used a single phospholipid, dipalmy-toylphosphatidylethanolamine, which is the major constituent of the inner membrane in Escherichia coli. The first results show clearly the importance of the GTP-controlled assembly process in the appearance of circular or fibrillar structures. (C) 2002 Elsevier Science B.V. All rights reserved.
