Enzyme activity: ThermoPhage Ts Lysozyme promotes lysis of certain bacteria probably through hydrolysis of linkages between sugar residues and peptides of the cell wall peptidoglycan. 

Synonyms: muramidase, N-acetylmuramide glycanhydrolase, glycoside hydrolase


Enzyme classification: EC


Source: Thermophilic bacteriophage Ph2119


Description: ThermoPhageLysozyme originates from a thermophilic bacteriophage known to infect thermophilic bacteria of the genus Thermus. The enzyme promotes lysis of certain bacterial species but has activity spectrum very different from the commonly used Hen egg white lysozyme (HEWL). The enzyme has high activity against bacteria of the genus Thermus including Thermusthermophilus and Thermus aquaticus as shown in the Table:

 Bacterial species Ts Lysozyme  HEWL
 Thermus thermophilus HB8  100  43
 Thermus aquaticus  100  41
 Deinococcus radiodurans  25  21
 Echerichia coli  34  100
 Salmonella panama  10  35
 Pseudomonas fluorescence  13  40
 Serratia marcescens  0  35
 Enterococcus faecalis  4  0
 Bacillus subtilis  2  0
 Bacillus cereus  15  75
 Staphylococcus aureus  0  0
 Staphylococcus intermedius  0  5
 Staphylococcus epidermis  0  0
 Sarcina lutea  2  48
 Streptococcus pyogenes  0  11
 Lactococcus lactis  0  11

Applications: The enzyme is suitable for efficient lysis of Thermus bacteria such as for increasing total DNA or plasmid DNA isolation (See figure below). Reactions and enzyme dilutions can be done in a 10 mM K/PO4 buffer at pH 8.0. The use of EDTA is not recommended.


DNA isolation: ThermoPhage™ Lysozyme improves plasmid preparation from Thermus thermophilus HB8
