Research Abstract |
It was shown that MreB helical structures were clearly visualized by staining with a newly synthesized anthracene-labeled A22 derivative in living E.coli cells. This provides the simple method observing bacterial actin-like cytoskeletons. We found that A22 induced cell lysis in E.coli mrcB mutant cells lacking PBP1B, one of the major penicillin-binding proteins. mreB(ts) mrcB double mutant lysed immediately upon temperature up-shift. These results indicate that simultaneous defects of MreB and PBP1B cause cell lysis.
