Correction for Crotty et al., Reexamination of magnetic isotope and field effects on adenosine triphosphate production by creatine kinase

PMCID: PMC3344953

BIOCHEMISTRY, PHYSICS Correction for “Reexamination of magnetic isotope and field effects on adenosine triphosphate production by creatine kinase,” by Darragh Crotty, Gary Silkstone, Soumya Poddar, Richard Ranson, Adriele Prina-Mello, Michael T. Wilson, and J. M. D. Coey, which appeared in issue 5, January 31, 2012, of Proc Natl Acad Sci USA (109:1437–1442; first published December 23, 2011; 10.1073/pnas.1117840108).

The authors note that on page 1441, left column, first paragraph, lines 8–11, “All trace metals in our reaction solutions were found to be below 0.5 μg/mL by ICP-MS, except Fe which was present at 14.6 and 9.7 μg/mL in the *Mg and 25Mg solutions, respectively” should instead appear as “All trace metals in the TCD reaction solutions were found to be below 0.5 μg/mL, including Fe which was present at 0.05 and 0.36 μg/mL in the *Mg and 25Mg solutions, respectively.”

The authors had reported an analysis of a pair of reaction solutions used in the TCD experiments, which indicated a remarkably high iron content. Subsequently, it was suggested that the inability of both the TCD and UE teams to reproduce the magnetic field and Mg isotope effects on ATP production by creatine kinase was due to iron contamination (1). A reexamination of the solution in question by an independent commercial service using ICP-ES analysis revealed an error in the original assay. The authors are grateful to Anatoly Buchachenko and Dimitri Kuznetsov for pointing out the error. This error does not affect the conclusions of the article.
