What is it about?
The power of X-ray crystal structure analysis as a technique is to ‘see where the atoms are’ but have you wondered what the estimated error on the coordinate of any atom in a protein and/or nucleic acid actually is? Our paper and web tool provides this either for a deposited PDB coordinate file or one that you are preparing.
Why is it important?
The end point of protein structure model refinement requires a knowledge of the individual atomic position errors. An online computing server to estimate the atomic coordinate errors for all the atoms in any protein structure is at the URL http://cluster.physics.iisc.ernet.in/dpi/. It can be used where restraints of a protein model refinement are not applied eg ion pairs or for metal ligands or protonation state determinations when a bond distance restraint is removed. This is important!
