In vivo characterization of Escherichia coli ftsZ mutants: effects on Z-ring structure and function.

Abstract excerpt

We have characterized the in vivo phenotypes of 17 mutations of Escherichia coli ftsZ. In particular, we determined whether these mutations can complement a null ftsZ phenotype, and we demonstrated that two noncomplementing mutations show partial dominant-negative behavior. We performed immunofluorescence microscopy to determine whether these mutants could assemble into normal or abnormal structures in vivo. The...
