HP1 family phage holin

Phage_holin_2_3 is a family of small hydrophobic phage proteins called holins with one transmembrane domain. Holins are produced by double-stranded DNA bacteriophages that use an endolysin-holin strategy to achieve lysis of their hosts. The endolysins are peptidoglycan-degrading enzymes that are usually accumulated in the cytosol until access to the cell wall substrate is provided by the holin membrane lesion 1,2]. [1]. 8710508.

phage holin

The pinholin type of holin produces a membrane hold just large enough to cause a membrane depolarization that triggers release of Sec-secreted endolysin from the inner membrane, activating the enzyme. This holin mechanism differs from that of holins that actually disrupt membrane enough to provide endolysin access to the cell wall.
