9.b.319. The DUF1656 Potential Actinobacterial Antimicrobial Peptide (DUF1656) Family
This family came up when a eukaryotic antimicrobial peptide (TC# 1.C.34.3.1) was BLASTed against the NCBI protein database. Although it was not apparently homologous, the actinobacterial protein had thousands of homologues, mostly from actinobacteria. They are mostly of about 80 aas in length.
