Synonyms: muramidase, N-acetylmuramide glycanhydrolase, glycoside hydrolase
Enzyme classification: EC 22.214.171.124
Source: Thermophilic bacteriophage Ph2119
Description: ThermoPhage™ Lysozyme 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|
Thermostability: Relative activity of ThermoPhage™ Lysozyme at different temperature vs. the activity of Hen Egg White Lysozyme
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.
