PDBREPORT

The PDBREPORT database is a weekly maintained database of observed anomalies in PDB files. In a way, PDBREPORT entries can be seen as error reports for macromolecular structures deposited in the PDB. The term error report should be used with caution as the WHAT_CHECK software that produces the PDBREPORT flags every anomalie of four sigma or more as an error. Obviously, some of the four sigma deviations are going to be genuine deviations from the mean rather than errors. Nevertheless, the PDBREPORTS are a useful facility for judging the quality of protein structures in in silico protein structure bioinformatics projects.
