|Comment||The characterized member of this family is the death-on-curing (DOC) protein of phage P1. It is part of a two protein operon with prevents-host-death (phd) that forms an addiction module. DOC lacks homology to analogous addiction module post-segregational killing proteins involved in plasmid maintenance. These modules work as a combination of a long lived poison (e.g. this protein) and a more abundant but shorter lived antidote.
Members of this family have a well-conserved central motif HxFx[ND][AG]NKR.
A similar region, with K replaced by G, is found in the huntingtin interacting protein (HYPE) family.|
RT Plasmid addiction genes of bacteriophage P1: doc, which causes cell death on curing of prophage, and phd, which prevents host death when prophage is retained.
