Biochemical and molecular characterization of a detergent-stable serine alkaline protease from Bacillus pumilus CBS with high catalytic efficiency.
TL;DR: The purified recombinant enzyme (rSAPB) has the same physicochemical and kinetic properties as the native one and is strongly inhibited by PMSF and DFP, showing that it belongs to the serine proteases superfamily.

Biocatalysts: application and engineering for industrial purposes.
TL;DR: The present review seeks to highlight the major fields of enzyme application and to provide an updated overview on previous protein engineering studies wherein natural enzymes were modified to meet the operational conditions required for industrial application.

Cloning, purification and biochemical characterization of metallic-ions independent and thermoactive l-arabinose isomerase from the Bacillus stearothermophilus US100 strain.
Moez Rhimi,Samir Bejar +1 more
TL;DR: The araA gene encoding L-arabinose isomerase from Bacillus stearothermophilus US100 strain was cloned, sequenced and over-expressed in E. coli and under reducing and non-reducing conditions, the recombinant enzyme has an apparent molecular weight of nearly 225 kDa.
