Structural Basis for BABIM Inhibition of Botulinum Neurotoxin Type B Protease [J. Am. Chem. Soc. 2000, 122, 11268-11269]. Michael A. Hanson, Thorsten K. Oost, Chanokporn Sukonpan, Daniel H. Rich, Raymond C. Stevens* Page 11268. After a detailed analysis of the electron density maps for the structure of the inhibitor complex, we have concluded that the maps do not support the placement of the inhibitor as stated in the paper. Therefore, we are withdrawing the structural conclusions derived from PDB file 1FQH presented in the paper. JA025109G 10.1021/ja025109g Published on Web 08/03/2002
