carica/protease

In this study, we characterized protease activities of 23 Ficus carica cultivars. Extracts of fruit, branch, and leaf of Masui Dauphine, one of the most representative F. carica cultivars in Japan, exhibited gelatin-hydrolyzing activity, both in the absence and presence of a cysteine

We investigated the effect of proteases derived from Ficus carica (common fig) on human blood coagulation. The milky sap (latex) of several Ficus (F.) species contain ficin, which is a mixture of proteases. Ficin derived from Ficus carica shortened the activated partial thromboplastin time and the

A Kunitz-type protease inhibitor purified from the latex of green papaya (Carica papaya) fruits was crystallized in the presence and absence of divalent metal ions. Crystal form I, which is devoid of divalent cations, diffracts to a resolution of 2.6 A and belongs to space group P3(1) or P3(2). This

Current outbreak of dengue has shown serious health concerns in Pakistan. The present study reports the anti-dengue potential of Carica papaya natural compounds. The leaves of C. papaya have previously shown promising results in cure of Dengue fever. The aim of this project is to find specific

A novel collagenolytic serine protease was identified and then purified (along with ficin) to apparent homogeneity from the latex of fig (Ficus carica, var. Brown Turkey) by two step chromatographic procedure using gel and covalent chromatography. The enzyme is a monomeric protein of molecular mass

Ficus carica is one of the most popular and edible plants. Its trees emanate latex of high medical importance. The well-studied procoagulant effect of ficin is a hallmark of this latex which protrudes an interesting question of how can the plant control this effect? In the present work, we

The latex of the common fig (Ficus carica) contains a mixture of at least five cysteine proteases commonly known as ficins (EC 3.4.22.3). Four of these proteases were purified to homogeneity and crystals were obtained in a variety of conditions. The four ficin (iso)forms appear in ten different

Dengue virus belongs to the virus family Flaviviridae. Dengue hemorrhagic disease caused by dengue virus is a public health problem worldwide. The viral non structural 2B and 3 (NS2B-NS3) protease complex is crucial for virus replication and hence, it is considered to be a good anti-viral target.

Papain-like cysteine proteases (PLCPs), a large group of cysteine proteases structurally related to papain, play important roles in plant development, senescence, and defense responses. Papain, the first cysteine protease whose structure was determined by X-ray crystallography, plays a crucial role

BACKGROUND The physiological role of fig latex is to protect the plant from pathogens. Latex is a rich source of proteases, predominantly ficin. Fig latex also contains collagenolytic protease and chitinolytic enzymes. Our aim was to investigate changes in protein composition, enzyme and antifungal

Triacylglycerol (TAG) lipases have been thoroughly characterized in mammals and microorganisms, whereas very little is known about plant TAG lipases. The lipolytic activity occurring in all the laticies is known to be associated with sedimentable particles, and all attempts to solubilize the

Cysteine proteinases from the Caricaceae belong to the C1 family of the CA clan and display papain-like structured, the archetype enzyme for this group of proteins. Carica candamarcensis, also named Vasconcellea cundinamarcensis, a member of Caricaceae family common to many areas in South America,

The dried latex of the mountain papaya, Carica candamarcensis, was chromatographed on CM-Sephadex C50, giving rise to three peaks (CCI, CCII and CCIII) with amidase activity on N-alpha-benzoyl-DL-arginine-4-nitroanilide. The less basic, most active, peak, CCI, was separated into two components, CCIa

The mechanical wounding impact on the Carica papaya latex protein pattern was investigated by analyzing three latexes. A first one commercially available, a second harvested from unripe but fully grown fruits, both obtained from regularly tapped fruits. A third one was collected from similar fruits

Papaya meleira virus (PMeV) is so far the only described laticifer-infecting virus, the causal agent of papaya (Carica papaya L.) sticky disease. The effects of PMeV on the laticifers' regulatory network were addressed here through the proteomic analysis of papaya latex. Using both 1-DE- and
