In the above-noted article, on p. 1697, in the third and fourth lines of the Abstract, the notation “YapD” should be written as “YadP.” On p. 1699, column 1, third line from the top, “the yapD open reading frame” should be “the yadP open reading frame”; in the next paragraph, “the E. coli enzyme YapD/LigT” should be “the E. coli enzyme YadP/LigT.”
The authors apologize for these errors. These errors have been corrected in the versions online.
