The best result was obtained from crystals of Ca2+ ATPase [adenosin-5'-([beta],[gamma]-methylene) triphosphate complex] which diffracted out to 7 Å resolution. Data were recorded at a wavelength at which the real resonant scattering factor of phosphorus reaches the extreme value of -20 electron units. The positions of the four triphosphates of the monoclinic unit cell of the ATPase have been obtained from a difference Fourier synthesis based on a limited set of anomalous diffraction data.}, note = {Online available at: \url{https://doi.org/10.1107/S0909049509025692} (DOI).
