Function | Involved in lysis inhibition. Senses superinfections and inhibits the holin, thereby delaying the host cell lysis timing. The genomic DNA from the superinfecting phage bound to the complex holin-antiholin probably serves as a signal for the lysis inhibition and blocks the holin multimerization. |
Subunit | Homotetramer; in free-form. Homomultimer. Heterotetramer composed of 2 holin and 2 antiholin. The holin-antiholin complex binds dsDNA. Interacts (via C-terminus) with holin (via C-terminus); this interaction blocks the holin homomultimerization and delays the host cell lysis. |
Subcellular location | Host periplasm. |
case <FTTag:disulf>
Ptm | Disulfide bond is required for functionality. |
