生化／生理作用
无花果蛋白酶（Ficin）被归类为硫醇蛋白酶。它的活性位点上含有单个反应性半胱氨酸。其活性位点的氨基酸同源性与木瓜蛋白酶相似。无花果蛋白酶将切割Gly、Ser、Thr、Met、Lys、Arg、Tyr、Ala、Asn和Val羧基侧的蛋白质。据报道，显色底物pGlu-Phe-Leu-p-硝基苯胺的 Km 为0.43 mM。无花果蛋白酶可被碘乙酰胺、碘乙酸、N-乙基马来酰亚胺、氯化汞、DFP（二异丙基氟磷酸酯）、TLCK（Na-对甲苯磺酰基-赖氨酸氯甲基酮）和TPCK（N-甲苯磺酰基-L-苯丙氨酸氯甲基酮）抑制。无花果蛋白酶可用于以高得率产生小鼠IgG1的F (ab′)2 片段。
單位定義
一个酶活性单位是指在测量酪蛋白的TCA可溶性产物时，在终体积为10ml（1cm光路）、37°C、pH 7.0条件下每分钟产生1.0的ΔA280 所需的酶量。
该酶溶于1 M磷酸钾缓冲液中，pH 7.0 (0.25 mg/ml)，得到澄清溶液。

Ficin is classified as a sulfhydryl protease isolated from the latex of fig trees. In most cases, a particular enzyme fits a few types of substrate and catalyzes one type of reaction. In this investigation, we found sufficient proofs for

Effect of pH on the conformational behaviour of ficin (EC 3.4.22.3), a cysteine protease from the latex of Ficus carica was monitored by circular dichroism, fluorescence spectroscopy, ANS binding and hydrodynamic studies. The results obtained from near- and far-UV CD

The development of inhibitory antibodies is a serious complication in hemophilic patients, severely compromising therapeutic success. Bleeding episodes in affected patients are controlled by treatment with a plasma-derived prothrombin complex concentrate (PCC), activated PCC (APCC) or recombinant activated factor VII.

The possibility of a slow post-acylation conformational change during catalysis by cysteine proteinases was investigated by using a new chromogenic substrate, N-acetyl-Phe-Gly methyl thionoester, four natural variants (papain, caricain, actinidin and ficin), and stopped-flow spectral analysis to monitor the pre-steady

On the basis of cDNA sequences, we found that the calli of rice encodes an amino acid sequence that shares 56% and 89% identity, respectively, with oryzacystatin-I and oryzacystatin-II. This sequence differs from that of oryzacystatin-II in the N-terminal region
