The BAltic Gene Set gene catalogue v1.1 encompasses 66,530,673 genes.

The 66 million genes are based on metagenomic data from Alneberg at al. (2020) from 124 seawater samples, that span the salinity and oxygen gradients of the Baltic Sea and capture seasonal dynamics at two locations. To obtain the gene catalogue, we used a mix-assembly approach described in Delgado et al. (2022).

The gene catalogue has been functionally and taxonomically annotated, using the Mix-assembly Gene Catalog pipeline ( The taxonomy annotation was performed using Mmseqs2[1] (uniref90[2]) and CAT[3] (GTDB[4]).

Here you find representative mix-assembly gene and protein sequences, and different types of annotations for the proteins. Also, contigs for the co-assembly are included (see Delgado et al. 2022), gene and protein sequences from each individual assembly and the co-assembly, and a table containing the genes in each of the clusters. See README for details.
