AB  - BACKGROUND: Actinidin is a cysteine protease and major allergen from kiwi fruit. When purified under specific native conditions, actinidin preparations from fresh kiwi fruit contain both an active and inactive form of this enzyme. In this study, biochemical and immunological properties upon simulated gastro-intestinal digestion, as well as thermal stability, were investigated for both active and E-64-inhibited actinidin. RESULTS: Active actinidin retained its primary structure and proteolytic activity after 2 h of simulated gastric digestion, followed by 2 h of intestinal digestion, as assessed by SDS-PAGE, zymography and mass spectroscopy. Immunological reactivity of active actinidin was also preserved, as tested by immunoelectrophoresis. The E-64 inhibited actinidin was fully degraded after 1 h of pepsin treatment. Differential scanning calorimetry showed that active actinidin has one transition maximum temperature (T-m) at 73.9 degrees C, whereas in the E-64-actinidin complex the two actinidin domains unfolded independently, with the first domain having a T-m value of only 61 degrees C. CONCLUSION: Active actinidin is capable of reaching the intestinal mucosa in a proteolytically active and immunogenic state. Inhibitor binding induces changes in the actinidin molecule that go beyond inhibition of proteolytic activity, also influencing the digestion stability and T-m values of actinidin, features important in the characterisation of food allergens.

AB  - Actinidin, a cysteine protease accounting for more than 50% of the soluble proteins in kiwifruit pulp, has shown promise as a milk-clotting agent. In this study, the potential use of kiwifruit pulp extract as a clotting agent was investigated. It was shown that three kiwifruit extracts made from the pulp of a single fruit have significantly different levels of active actinidin, depending on the extraction buffer employed. Kiwifruit extract prepared at pH 5.0 had the best milk-clotting properties, with a nearly 30% better ratio of clotting activity to proteolytic activity than purified actinidin. This extract produced a casein coagulum clearly separated from the whey proteins, and was shown to be stable at room temperature for up to two months. This extract has the potential to be employed as an efficient and low-cost milk-clotting agent in the production of dairy products.

AB  - The need for replacing traditional pesticides with alternative agents for the management of agricultural pathogens is rising worldwide. In this study, a cysteine proteinase inhibitor (CPI), 11 kDa in size, was purified from green kiwifruit to homogeneity. We examined the growth inhibition of three plant pathogenic Gram-negative bacterial strains by kiwi CPI and attempted to elucidate the potential mechanism of the growth inhibition. CPI influenced the growth of phytopathogenic bacteria Agrobacterium tumefaciens (76.2 % growth inhibition using 15 mu M CPI), Burkholderia cepacia (75.6 % growth inhibition) and, to a lesser extent, Erwinia carotovora (44.4 % growth inhibition) by inhibiting proteinases that are excreted by these bacteria. Identification and characterization of natural plant defense molecules is the first step toward creation of improved methods for pest control based on naturally occurring molecules.

AB  - For the heterologous production of a banana glucanase in Escherichia coli, its gene (GenBank GQ268963) was cloned into a pG EX-4T expression vector as a fusion protein with glutathione-S-transferase (GST). BL21 cells transformed with the GST-Mus a 5 con struct were employed for production of the protein induced by 1 mM isopropyl-β-D-thiogalactopyranoside (IPTG). The conditions for protein expression were optimized by varying the temperature (25, 30 and 37°C) and duration of protein expression (3, 6 and 12 h). The level of protein production was analyzed by densitometry of the sodium dodecyl sulfate-polyacrylamide gel (SDS-PAG) after electrophoretic resolution of the respective cell lysates. The optimal protein expression for downstream processing was obtained after 12 h of cell growth at 25°C upon addition of IPTG. Recombinant GST-Mus a 5 purified by glutathione affinity chromatography revealed a molecular mass of a bout 60 kDa. The IgE and IgG reactivity of the rGST-Mus a 5 was confirmed by dot blot an analysis with sera of individual patients from subjects with banana allergy and polyclonal rabbit antibodies against banana extract, respectively. The purified recombinant glucanase is a potential candidate for banana allergy diagnosis.

AB  - Actinidin, an abundant cysteine protease from kiwifruit, is a specific biomarker of isolated allergy to kiwifruit. This study evaluates the IgE-binding properties of biologically active and thermally inactivated actinidin. Employing two different activity assays (caseinolytic assay and zymogram with gelatin) we showed that actinidin obtained from kiwifruit extract under native conditions represents a mixture of inactive and active enzyme. The structural integrity of actinidin was confirmed by SDS-PAGE. Edman degradation, mass fingerprint and Western blot with polyclonal antibodies. Although it was capable of inducing positive skin prick test reactions, we failed to detect IgE reactivity of active actinidin in Western blot with patient sera. Thermally inactivated actinidin exhibited IgE reactivity both in vivo and in vitro, indicating that heat processed kiwifruit products may induce clinical reactivity. These findings imply that apart from the allergenic epitopes on its surface, actinidin also contains hidden epitopes inside the protein which become accessible to IgE upon thermal treatment.

This study evaluates the IgE-binding properties of biologically active and thermally inactivated actinidin. Employing two different activity assays (caseinolytic assay and zymogram with gelatin) we showed that actinidin obtained from kiwifruit extract under native conditions represents a mixture of inactive and active enzyme. The structural integrity of actinidin was confirmed by SDS-PAGE. Edman degradation, mass fingerprint and Western blot with polyclonal antibodies. Although it was capable of inducing positive skin prick test reactions, we failed to detect IgE reactivity of active actinidin in Western blot with patient sera. Thermally inactivated actinidin exhibited IgE reactivity both in vivo and in vitro, indicating that heat processed kiwifruit products may induce clinical reactivity. These findings imply that apart from the allergenic epitopes on its surface, actinidin also contains hidden epitopes inside the protein which become accessible to IgE upon thermal treatment.
