alpha-Aspartate 261 is a key residue in noncatalytic sites of Escherichia coli F1-ATPase.

The Journal of biological chemistry - 8 Sept 1995

Weber J, Bowman C, Wilke-Mounts S, Senior A E

Abstract excerpt

X-ray structure analysis of the noncatalytic sites of F1-ATPase revealed that residue alpha-Asp261 lies close to the Mg of bound Mg-5'-adenylyl-beta,gamma-imidodiphosphate. Here, the mutation alpha D261N was generated in Escherichia coli and combined with the alpha R365W mutation, allowing nucleotide binding at F1 noncatalytic sites to be specifically monitored by tryptophan fluorescence spectroscopy. Purified...
