Accession ID Name Pfam Type
PF08272 Topoisomerase I zinc-ribbon-like domain

Some Proteobacteria topoisomerase I contain two zinc-ribbon-like domains at the C-terminus that structurally homologous to Pfam:PF01396. However, this domain no longer bind zinc. Indeed, only one of the four cysteine residues remains [1].
