a
* indicates that the FtsZ derivative is unstable.
b
The FtsA-FtsZ interaction shown was tested in JFL101 (ftsZ84). +, strong fluorescent spirals; −, no strong fluorescent spirals.
c
See legend to Table 4 for explanation of the data.
d
The results of ZipA-FtsZ interaction shown here were examined in both JFL101 (ftsZ84) and WM1099 (ftsZ depletion) strains. NT, not tested.
