Figure 1. Deposition of atomic or near-atomic-resolution structures in the Protein Data Bank according to different experimental methods.

( A) The number of structures deposited annually is shown between 2010 and the end of 2019, based on X-ray diffraction, cryo-electron microscopy (EM), and NMR methods. A sub-4 Å resolution criterion was imposed (for X-ray and EM). The inset shows the depositions since 2015 on a logarithmic scale. ( B) The same set of structures are broken down by resolution. Those based on EM do not include those determined by electron diffraction methods (see Figure 4).
