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
PQI has 3213 proteomes, each with quality determined by up to 11 combined metrics. Each proteome can be downloaded to a FASTA formatted file
