Searches for structures in the specified resolution range. A histogram icon next to the search box links to a histogram that shows the distribution of resolution in the PDB.
Resolution is a measure of the underlying data quality in a diffraction experiment and represents the level of detail present in the diffraction pattern. High-resolution structures have low R values around 1 Å, whereas lower resolution structures are around 3 Å and above. See the "Looking at Structures: Resolution" page (here) for more details.
Note: non-diffraction methods such as NMR do not have a resolution specified.
Search by resolution range
Between: 1.5 and 2.0
This query retrieves structure in the 1.5 - 2.0 resolution range.
Use the resolution histogram
Click on the histogram icon to display a histogram of the resolution distribution for PDB structures. Mouse over a bar in the histogram to display the number of structure in the resolution range. The structures corresponding to the bar can be viewed by clicking on the icon to the right of the histogram.
