1.E.67.1.1
Holin of Pseudomonas lytic phage HZ2201 of 72 aas and 2 TMSs.  This phage shows antibiofilm efficacy against P. aeruginosa (Fei et al. 2023). See family description for details.  This protein is (nearly) identical to the holin from phage PaP3 except for 22 N-terminal amino acids  with a third TMS in the latter protein (GenBank acc # NP_775222.1) that are lacking in 1.E.67.1.1.  It is likely that the 1.E.67.1.1 protein is N-terminally truncated, as all other members of the family are longer with 3 TMSs.
