Proteome Quality Index

PQI is measure of proteome quality available from a comprehensive database of downloadable proteomes. Completely sequenced genomes for which there is an available set of protein sequences (the proteome) are given a 5-star rating supported by 11 different metrics of quality.

PQI is a constantly updated web resource that currently includes over 3,200 annotated proteomes from multiple providers including all entries from NCBI and ENSEMBL, powered by the SUPERFAMILY Database
