What is "metaproteomics"

n. (context biochemistry English) The branch of molecular biology that studies the set of metaproteins of an organism

Metaproteomics (also Community Proteomics, Environmental Proteomics, or Community Proteogenomics) is the study of all protein samples recovered directly from environmental sources. Metaproteomics is used to classify experiments that deal with all the genes and proteins identified from complex communities, where individuals cannot be binned into species or organisms types. The metaproteomics approach is comparable to gene-centric environmental genomics, or metagenomics.
