BP holin family
The β-proteobacterial holin family is a small family that includes members derived from a number of Burkholderia phage as well as a Poloromonas species. As of April 3, 2016, this family belongs to the Holin superfamily II. Members of at University of California, San Diego found that the BP-Hol family is most closely related to the T7 holin family. These proteins are of 60 to 110 amino acyl residues in length and exhibit 1 or 2 transmembrane segments. Some are annotated as type II hollins and may be related to members of the T7 Holin family, although BP-Hol proteins remain functionally uncharacterized. A representative list of the proteins belonging to the BP-Hol family can be found in the .
