The enzyme is deacylated by a water molecule and releases the carboxy terminal portion of the peptide. In immunology, papain is known to cleave the Fc (crystallisable) portion of immunoglobulins (antibodies) from the Fab (antigen-binding) portion. Papain is a relatively heat-resistant enzyme, with an optimal temperature range of 60 to 70 °C. [9]
Caricain can be assayed with Bz-ArgkNHPhNO2, kcat/Km being 187 M21 s21 at pH 6.8 and 40˚C. More sensitive substrates may employ a fluorometric leaving group, kcat/Km for the hydrolysis of Z-Phe-ArgkNHMec being 1.06 3 106 M21 s21 (pH 6.8, 40˚C). [5] The enzyme exhibits a broad pH-activity profile, with the optimum near 7.0.

Under the 5:2, women eat less than 500 calories a day for two non-consecutive days a week (for men, it’s less than 600). Then, you eat normally the other days a week.
Actinidain (EC 3.4.22.14, actinidin, Actinidia anionic protease, proteinase A2 of Actinidia chinensis) is a type of cysteine protease enzyme found in fruits including kiwifruit (genus Actinidia), pineapple, mango, banana, figs, and papaya. This enzyme is part of the peptidase C1 family of papain-like proteases. [1] [2] [3] [4]
