摘要

The bacterial cell division protein FtsZ is a homolog of tubulin, but it has not been determined whether FtsZ polymers are structurally related to the microtubule lattice. In the present study, we have obtained high-resolution electron micrographs of two FtsZ polymers that show remark- able similarity to tubulin polymers. The first is a two- dimensional sheet of protofilaments with a lattice very similar to that of the microtubule wall.
