In those studies involving bacteria, lytB was found to be related to nutritional- and temperaturestress response, and it was reported to encode a pneumococcal murein hydrolase, which plays an important role in cell division (Wosten et al., 1997).

The organism contains a large amount of Murein monomer precursors and has a thickened cell wall.
Hilpert et al [30] found that archaea were insensitive to many antibiotics that act against eubacteria and eukaryotes, such as those inhibiting the synthesis or cross-linkage of the peptide subunit of murein or those that inhibit the synthesis of RNA.
None of the other flagellar biosynthetic proteins that are found in other enteric bacteria, such as FlhB, FlhA, FlhF, FliP, FliQ and FliR, except for flagellar biosynthetic protein FliZ (RWLH00696) and murein transglycosylase (RWLH04013, RWLH05152), was identified in this genome.

These proteins are believed to be enzymes that catalyze the terminal stages of murein synthesis and are inhibited by covalent bonding with penicillin at their active site.
The antibacterial activity of YML might be attributed to its capacity to disrupt bacterial murein. This indicated that the milk lysozyme still can be used as an antibacterial peptide although ruminant milk have lysozyme deficiency.
