Mechanistic Studies of a Retaining R-Galactosyltransferase from Neisseria meningitidis, by Hoa D. Ly, Brenda Lougheed, Warren W. Wakarchuk, and Stephen G. Withers,* Volume 41, Number 16, April 23, 2002, pages 5075-5085. Page 5084. The Note Added in Proof should have appeared as follows. A recent determination of the structure of the bovine galactosyltransferase (43) casts serious doubts upon the conclusions of the paper by Gastinel et al. (15) concerning the formation of a covalent intermediate. BI025160X 10.1021/bi025160x Published on Web 04/26/2002
