abstract = {Halophilic and halotolerant microorganisms represent a
promising source of salt-tolerant enzymes suitable for
various biotechnological applications where high salt
concentrations would otherwise limit enzymatic activity.
Considering the current growing enzyme market and the need
for more efficient and new biocatalysts, the present study
aimed at the characterization of a high-alkaline subtilisin
from Alkalihalobacillus okhensis Kh10-101T. The protease
gene was cloned and expressed in Bacillus subtilis DB104.
The recombinant protease SPAO with 269 amino acids belongs
to the subfamily of high-alkaline subtilisins. The
biochemical characteristics of purified SPAO were analyzed
in comparison with subtilisin Carlsberg, Savinase, and BPN'.
SPAO, a monomer with a molecular mass of 27.1 kDa, was
active over a wide range of pH 6.0–12.0 and temperature
20–80 °C, optimally at pH 9.0–9.5 and 55 °C. The
protease is highly oxidatively stable to hydrogen peroxide
and retained $58\%$ of residual activity when incubated at
10 °C with $5\%$ (v/v) H2O2 for 1 h while stimulated at
$1\%$ (v/v) H2O2. Furthermore, SPAO was very stable and
active at NaCl concentrations up to 5.0 m. This study
demonstrates the potential of SPAO for biotechnological
applications in the future.},
