I am looking to find a way to map a list of biomarkers of interest, say genes or bacterial functions, to existing annotation databases. Usually this is done in reverse, as such that based on metagenomics profiling you can see which pathways or genes are present. However, I want to be able to determine which genes or pathways to extract beforehand i.e. as I think it will be quite difficult to condense pathways or genes of interest from annotation data.
Biomarker gene for better sleep - maps to annotation database at ... Biomarker gene for glucose metabolism - maps to annotation database at.. .. which in turn allows to directly quantify those biomarkers.
