BIOCHEMISTRY. For the article “RNA degradosomes exist in vivo in Escherichia coli as multicomponent complexes associated with the cytoplasmic membrane via the N-terminal region of ribonuclease E” by Gunn-Guang Liou, Wann-Neng Jane, Stanley N. Cohen, Na-Sheng Lin, and Sue Lin-Chao, which appeared in number 1, January 2, 2001, of Proc. Natl. Acad. Sci. USA (98, 63–68; First Published December 26, 2000; 10.1073/pnas.011535498), the authors note that the y axis label of Fig. 1B should read “picomoles/OD₆₀₀.” The corresponding text in the Fig. 1 legend on page 64 and the results described on page 66, line 2 from the bottom of the left-hand column, should also be in units of picomole per OD₆₀₀.
