We thank Michael Deras and Professor V. J. Davisson at Purdue University for synthesizing 2-iodo-adenosine-5′-diphosphate, a compound used to construct two heavy-atom derivatives of acetate kinase. The work of M.S.H. was funded by NIH award GM57056. The beginning of the project was supported by a Research Planning Grant from NSF and a March of Dimes grant to M.S.H.
