MICROBIOLOGY. For the article “Targeting cell division: Small-molecule inhibitors of FtsZ GTPase perturb cytokinetic ring assembly and induce bacterial lethality,” by Danielle N. Margalit, Laura Romberg, Rebecca B. Mets, Alan M. Hebert, Timothy J. Mitchison, Marc W. Kirschner, and Debabrata RayChaudhuri, which appeared in issue 32, August 10, 2004, of Proc. Natl. Acad. Sci. USA (101, 11821–11826; first published August 2, 2004; 10.1073/pnas.0404439101), the authors note that in line 13 on page 11824, under Zantrins Cause Bacterial Lethality, 2.5 μM should be 5 μM. Also, the symbols in the affiliation line appeared incorrectly. The corrected affiliation line appears below. The online version has been corrected.
