MICROBIOLOGY. For the article “Mycobacterial polyketide-associated proteins are acyltransferases: Proof of principle with Mycobacterium tuberculosis PapA5,” by Kenolisa C. Onwueme, Julian A. Ferreras, John Buglino, Christopher D. Lima, and Luis E. N. Quadri, which appeared in issue 13, March 30, 2004, of Proc. Natl. Acad. Sci. USA (101, 4608-4613; first published March 18, 2004; 10.1073/pnas.0306928101), due to a printer's error, the word “acyltransferase” incorrectly appeared as “acetyltransferase” in the eighth line of the abstract.
