 Putative holin-2 family

The Putative Holin-2 (PH-2) Family (TC# 9.B.154) is a large family with members from a wide variety of bacteria (i.e., "Roseifoexus", "Cupriavidus (Ralstonia)", "Opitutus", "Bacteroides, Pirellula").As of early 2016, functional data is not available for members of the PH-2 family, but based on their size and topology, it is believed they act as holins to facilitate cell lysis.
