The phage λ lysozyme (R Endolysin) hydrolyses the beta-1,4-glycosidic bond between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc), but in order to degrade the cell wall it requires a small transmembrane protein called holin which perforates the membrane for endolysin to gain access to the murein [Ry Young et al].

Bacteriophage Lysis Cassette with RBS

Bacteriophage Lysis cassette based on the part BBa_K124017 (note the overlapping coding regions of the sequence in spite of the given sequence for BBa_K124017) with an additional strong RBS (BBa_B0034)


Usage and Biology

The phage lysis cassette consists of the standard bacteriophage λ lysis genes S/S’, R and Rz/Rz1, coded in overlapping sequences with phase 1 and 2 frameshifts.


  • S: λ Anti-Holin
  • S’: λ Holin
  • R: λ Endolysin
  • Rz: Putative type-II signal anchor protein
  • Rz1: Outer membrane lipoprotein


The phage λ lysozyme (R Endolysin) hydrolyses the beta-1,4-glycosidic bond between N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc), but in order to degrade the cell wall it requires a small transmembrane protein called holin which perforates the membrane for endolysin to gain access to the murein [Ry Young et al]. The auxiliary lysis proteins Rz and Rz1 have long been known to play a vital role but have yet to be assigned a specific function stemming from functional and structural analysis. The assumption is that they form a complex spanning the periplasm and fuse the outer and inner membranes, removing the last physical barrier for cell lysis [Joel Berry et al].
