Supplied at ~ 275 U/mL

Purified from Carica papaya

Devoid of α-amylase, β-glucanase (cellulase), endo-1,4-β-xylanase and polygalacturonanase (determined by incubating high levels of the enzyme with pure polysaccharides in highly sensitive viscometric assays).

~ 9 U/mg (40^oC, pH 7.0 on N, N-dimethylcasein)

One Unit of activity is the amount of enzyme that will produce one µmole (181 µg) of tyrosine equivalents from N, N-dimethylcasein per minute at pH 7.0 and 40^oC (colour determined using the Folin-Ciocalteu reagent).
