Description

Enzymes work at high temperature with high reactivity The "Thermostable Enzyme".

Generally, enzymes in the living body are denatured and lose activities at the temperature over 50 - 60°C.
However, the thermostable enzymes obtained from special microorganisms (hyper-thermophilic microorganisms) alive at high temperature (over 70°C) have unique characteristics.

Using regular enzymes as a catalyst in chemical reactions are not cost effective due to its low stability and needs of additional enzyme.
By using these thermostable enzymes, we can expect not only cost saving but also other advantages - especially in the field of fine chemicals.

Features of Thermostable Enzyme

Highly stable and durable for long term use
High reactivity at high temperature (70 - 100°C)
Resistance to organic solvent is expected
Special instruments to inhibit bacterial growth are not required.
Reaction speficity is much higher compared with chemical reaction
Speed of reaction can be accelerated

Unit definition

1 U is defined as the amount of enzyme producing 1 µmol of p-nitrophenol per min from p-nitrophenyl-xylopyranoside (pNPX) in the assay condition (1 mM pNPX in 50 mM acetate buffer, pH 6.0).
