Abstract

•Homology-based proteomics, proteogenomics, metaproteomics rely on large protein sequence database.•Not all entries in a sequence database are of equal quality.•We exemplify database contamination with two examples: the bacterium Enterococcus gallinarum EGD-AAK12 and the insect Ceratitis capitata.•We incite database users to contribute to the overall quality of databases.

Advances in genome sequencing have made proteomic experiments more successful than ever. However, not all entries in a sequence database are of equal quality. Genome sequences are contaminated more frequently than is admitted. Contamination impacts homology-based proteomic, proteogenomic, and metaproteomic results. We highlight two examples in the National Center for Biotechnology Information non-redundant database (NCBInr) that are likely contaminated: the bacterium Enterococcus gallinarum EGD-AAK12 and the insect Ceratitis capitata. We hope to incite users of this and other databases to critically evaluate submitted sequences and to contribute to the overall quality of the database by signaling potential errors when possible.
