Application

Ficin from fig tree latex has been used:
  • in the proteolysis of tendon collagen
  • in the digestion of Chlorophyta Ulva rigida
  • to investigate it effect on protease-activated receptors 2 and 4 activation to induce itch in skin[1]

Biochem/physiol Actions

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 Km for the chromogenic substrate pGlu-Phe-Leu-p-nitroanilide is 0.43 mM. 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.
Ficin is effective in disrupting the staphylococcal biofilms making it accessible antibiotics exposure.

Physical form

Lyophilized powder containing L-cysteine and trace EDTA

Preparation Note

This enzyme is soluble in water (10 mg/ml), yielding a clear solution.

Other Notes

One unit will produce a ΔA280 of 1.0 per min at pH 7.0 at 37°C when measuring TCA soluble products from casein in a final volume of 10 ml (1 cm light path).

Preguntas

  1. What is this used for exactly? In lay terms please.

    1. Ficin is an enzyme that has a number of uses in several markets. As mentioned in the DESCRIPTION section of the product detail page, ficin from fig tree latex has been used:

      in the proteolysis of tendon collagen (tendons are softened in meat/muscles)
      in the digestion of Chlorophyta Ulva rigida (softens this algae which is used in 'sea salad' and animal feed)
      to investigate it's effect on protease-activated receptors 2 and 4 activation to induce itch in skin (studies indicate it can cause itching)
      in disrupting the staphylococcal biofilms, making it accessible antibiotics exposure. (Staph can be very resistant to antibiotics, particularly in 'biofilms'. Ficin digests or breaks down this film so that antibiotics are more effective.)

      It is also used in the food industry, primarily dairy products and is useful in clotting milk to aid in cheese production.
      Ficin has several medical uses, as well. This product is for research use only, however the link below describes some of the medical applications of Ficin:
