Expression, isolation, purification, and biochemical properties of trehalose-6-phosphate hydrolase from thermoresistant strain Bacillus sp. GP16.


PMID 14606945

Abstract

Here we describe cloning, expression, and purification of the enzyme trehalose-6-phosphate hydrolase from thermoresistant strain Bacillus sp. GP16. Principal biochemical properties of the enzyme at different pH and temperature values were determined. Entropy and enthalpy of activation of the enzyme for substrates trehalose-6-phosphate and p-nitrophenyl glucoside were calculated, and the dependence of the kinetic parameters from ionic strength was established.
