    Summary

    Pfam family PFAM:PF03713 {Domain of unknown function (DUF305)} with 1019 members in NR database and additional 702 members in the metagenomic datasets is represented in Bacteria, and Viruses. The first structural representative solved (PDB Id: TOPSAN:2qf9) was subject to FATCAT structural similarity search that indicated similarity to SCOP (v. 1.73) domain SCOP:d1lkoa1 classified as Ferritin-like fold. Based on marginal prediction from FFAS confirmed by structural similarity one can argue that this family is remotely homologous to previously known structures from 'd1lkoa1' this fold. Based on existing annotations enhanced by fold and evidence of homology one can hypothesize that this family is ferritin secreted by bacteria ?
