actinidia/protease

An protease from Actinidia arguta for improving meat tenderness was purified, characterized from wild A. arguta fruit by ammonium sulfate precipitation, Sephdex G-25 gel filtration chromatography, and DEAE Sepharose Fast Flow ion exchange chromatography, and its activity was investigated. The

Kiwifruit (Actinidia chinensis) contains abundant protease, actinidin, and two possible components which were named A1 and A2. However, a comparison of the two components has not been thoroughly conducted. We have previously shown the presence of six proteases named KP1, KP2, KP3, KP4, KP5 and KP6

Actinidin, a kiwifruit cysteine protease, is a marker allergen for genuine sensitization to this food allergen source. Inhalatory cysteine proteases have the capacity for disruption of tight junctions (TJs) enhancing the permeability of the bronchial epithelium. No such properties have been reported

Cysteine proteases (CPs) accumulate to high concentration in many fruit, where they are believed to play a role in fungal and insect defense. The fruit of Actinidia species (kiwifruit) exhibit a range of CP activities (e.g. the Actinidia chinensis variety YellowA shows less than 2% of the activity

Raphides, needle-shaped calcium oxalate crystals in tissues of many plants, have been thought to play defensive roles against herbivores without detailed bioassays for their defensive roles and modes of function using purified raphides. In order to examine the defensive roles and modes of function

In this report a full-length cDNA, SPCP2, which encoded a putative papain-like cysteine protease was isolated from senescent leaves of sweet potato (Ipomoea batatas). SPCP2 contained 1101 nucleotides (366 amino acids) in its open reading frame, and exhibited high amino acid sequence identities (ca.

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

Major Phytoconstituents of Actinidia deliciosa were explored for their anti-viral potential against dengue virus (DENV). The docking of these phytoconstituents was performed on 7 viral targets- 4 DENV non structural protein (NS5-SAM binding domain, NS5 RdRp domain, NS3 helicase & NS2B-NS3

A current limitation in the use of fast atom bombardment (FAB) mass spectrometric mapping of peptide mixtures, derived from enzymic digestion of proteins, is that most of the hydrophilic peptides are not observed. However, it has been demonstrated from previous work that esterification of the

Procerain B, a novel cysteine protease (endopeptidase) isolated from Calotropis procera belongs to Asclepiadaceae family. Purification of the enzyme, biochemical characterization and potential applications are already published by our group. Here, we report cDNA cloning, complete amino acid

The structure of the 24 kDa cysteine protease saru-actinidin from the fruit of Actinidia arguta Planch. (sarunashi) was determined by the cadmium/sulfur-SAD method with X-ray diffraction data collected using in-house Cu Kα and Cr Kα radiation. The anomalous scatterers included nine sulfurs and

Kiwifruit is the most well-known crop in the genus Actinidia. Although Actinidia fruit sales in the international market are dominated by a single kiwifruit cultivar Actinidia deliciosa "Hayward," there are a considerable number of cultivars and selections in the genus that have widely diverse

BACKGROUND Allergic reactions to fruits and vegetables are among the most frequent food allergies in adults. Kiwi fruit (Actinidia chinensis) is commonly involved, causing local mucosal, systemic, or both types of symptoms by an IgE-mediated mechanism. In a previous study on 30 patients allergic to
