1.E.5.1.1
P35 holin of phage PRD1 (Rydman and Bamford 2003; Ziedaite et al. 2005).  This holin is up to 98% identical to the holins of plasmid-dependent tectiviruses (Quinones-Olvera et al. 2024). Cell death can be dependent on holins LrgAB repressed by a novel ArsR family regulator CdsR (Zhang et al. 2024).
