Article: Studies from Sichuan University provide new data on applied biochemistry.

"An alkaline protease (DHAP) from Bacillus pumilus has shown great potential in hide dehairing. To get better insights on its catalytic properties for application, the substrate specificity and thermostability were investigated using five natural proteins and nine synthetic peptides," scientists writing in the journal Applied Biochemistry and Biotechnology report.

"The results showed that DHAP could hydrolyze five proteins tested here in different specificity. Collagen, a component of animal skin, was more resistant to hydrolysis than casein, fibrin, and gelatin. Among the synthetic peptides, the enzyme showed activity mainly with tetrapeptide substrates with the ...
