How to retrieve the annotation for the structures displayed?

[AngelRuizMoreno]

Is there any way to get the information about the source organism, study or any other annotation for the predicted structures in ESM Metagenomic Atlas?

[tomsercu]

Actually there's not much known about those proteins, as the source organism is unknown (hence, "metagenomics", doesn't come from a single organism's genome). The proteins in MGnfy also don't necessarily come from a single study:

MGnify produces a non-redundant protein database that is generated from amalgamating all open reading frame predictions from the analysis of all of the underlying assembled datasets
