Description
Proteinase K from *Tritirachium album* is a broad-spectrum serine endopeptidase whose robust activity across denaturing conditions makes it indispensable for nucleic acid isolation, and this yeast-expressed recombinant form delivers a validated specific activity of >30 U/mg (tyrosine release assay, pH 7.5, 37 °C), providing a suitable basis for enzymatic activity assays, kinetic parameter analysis (Km, Vmax, kcat), and substrate specificity profiling. Stability testing over twelve months at 4 °C confirmed retention of >95% catalytic activity, supporting reliable use as a positive control in… Read more
