In the version of this article initially published, two arrows in the far right plot of Fig. 3c were aimed incorrectly, and the error bars were missing in Fig. 6e, f. In Fig. 3c, the arrow labeled ‘5-LOX’ should be aimed at the plot measuring LXB4, and the arrow labeled ‘LTA4H’ should be aimed at the plot measuring LTB4. The errors have been corrected in the HTML and PDF versions of the article.
