Distribution of the ln(Nref/Nat) value versus resolution dPDB on a uniform logarithmic scale. (a) Structures with Matthews coefficient 2.35 < VM < 2.45 Å3 Da−1. VM is taken from the file headers and data completeness is above 99%. The broken arrow shows the change in the ratio after a correct assignment of Nat for 1yqn . (b) The same as (a) but with VM recalculated. (c) The same as (b) but without selection of entries by data completeness. (d) The same as (c) but with correction for data completeness. (e) All models with data completeness above 99%. (f) Random selection from the whole PDB with correction for data completeness. The orange line corresponds to theoretical values for crystals with VM = 2.4 Å3 Da−1. The green, blue and yellow lines show the linear approximations for (a), (e) and (f), respectively.
