phage terminase small subunit

Members of this family are phage terminase small subunit proteins, based on adjacency to terminase large subunit proteins, and on a small N-terminal homology domain, described by PF10668, about 67 amino acids in length, shared with TerS from PBSX (XtmA) and from phage related to PBSX. Terminase small subunits related to XtmA of defective prophage PBSX have a C-terminal PF03592 domain, accounting for most of the length of those proteins. Members of this family differ from XtmA-like TerS over most of the their lengths, C-terminal to the PF10668 domain, and show no trace of homology to PF03592.
