This makes the determination of Ca2+-protein affinities an interesting subject for functional studies. We have investigated the performance of two methods ¨C Fold-X and AutoDock vina ¨C in the prediction of Ca2+-protein affinities. Both methods, although based on different energy functions, showed virtually the same correlation with experimental affinities. Guided by insight from experiment, we further derived a simple linear model based on thesolvent accessible surface of Ca2+ that had practically the same performance in terms of absolute errors as the more complex docking methods. %K metal ions %K binding %K free energy %K crystal structure %K solvent accessible surface %U https://www.dovepress.com/estimating-affinities-of-calcium-ions-to-proteins-peer-reviewed-article-AABC
