生物活性/药理作用

Ficin is classified as a thiol protease. It contains a single reactive cysteine at its active site. The amino acid homology of the active site is similar to that of papain. Ficin will cleave proteins at the carboxyl side of Gly, Ser, Thr, Met, Lys, Arg, Tyr, Ala, Asn, and Val. The reported K^m for the chromogenic substrate pGlu-Phe-Leu-p-nitroanilide is 0.43mM. Ficin is inhibited by iodoacetamide, iodoacetic acid, N-ethylmaleimide, mercuric chloride, DFP (diisopropyl fluorophosphate), TLCK (Na-p-Tosyl-lysine chloromethyl ketone), and TPCK (N-Tosyl-L-phenylalanine chloromethyl ketone). Ficin can be used to generate high yielding F(ab′)₂ fragments from mouse IgG1.

有效单位定义

One unit will produce a ΔA²⁸⁰ of 1.0 per min at pH7.0 at 37°C when measuring TCA soluble products from casein in a final volume of 10ml (1 cm light path). The enzyme is soluble in 1M potassium phosphate buffer, pH7.0 (0.25mg/ml), yielding a clear solution.
