peptidoglycan amidohydrolase
Uniprot IDB8QIR1
General Mode of ActionEnzymatic cleavage of peptidoglycan which results in a rapid lysis of the bacterial cell.
phiBIOTICS Family ?NAM amidase
Reaction ?1. Catalysis of the hydrolysis of the link between N-acetylmuramoyl residues and L-amino acid residues in certain bacterial cell-wall glycopeptides
    EC: 3.5.1.28
    Corresponding Pfam domain: Amidase_2
    Evidence: predicted (PubMed: 18809219)
2. Catalysis of the hydrolysis of the bonds in cell wall peptidoglycans (amidohydrolase/peptidase activity)
    EC: n/a
    Corresponding Pfam domain: CHAP
    Evidence: predicted (PubMed: 18809219)

LysH5 in vitro
  • set of various bacterial species including Staphylococcus aureus strains (human and bovine origin) and strains belonging to:
    Bacillus
    Streptococcus
    Clostridium
    Lactococcus
    Lactobacillus
    Leuconostoc
    Listeria
    Enterococcus
Lytic activity against all S. aureus strains tested irrespective of their origin, differences in killing efficacy were noted (higher susceptibility noted for bovine S. aureus strains). Efficient lytic activity was also achieved in milk, reducing bacterial viable titers to undetectable levels in 4 h.

No lytic activity against other various strains tested.
