Bioactive molecules of plant species are promising alternatives for the chemical control of gastrointestinal nematodes in ruminants. Extracts of native and exotic seed species from Brazil's semi-arid region were tested in vitro in an egg hatch assay and the bioactivity of their proteins was

Plant seeds are used to extract oil bodies for diverse applications, but oil bodies extracted at different pH values exhibit different properties. Jicama, sunflower, peanut, castor bean, rapeseed, and sesame were selected to examine the effects of pH (6.5-11.0) on the protein components of oil

Arabidopsis thaliana SAG12, a senescence-specific gene encoding a cysteine protease, is widely used as a molecular marker for the study of leaf senescence. To date, its potential orthologues have been isolated from several plant species such as Brassica napus and Nicotiana tabacum. However, little

The endosperm of castor bean seeds (Ricinus communis L.) contains two -SH-dependent aminopeptidases, one hydrolyzing l-leucine-beta-naphthylamide optimally at pH 7.0, and the other hydrolyzing l-proline-beta-naphthylamide optimally at pH 7.5. After germination the endosperm contains in addition an

During post-germinative seedling growth, the major storage organ of the white spruce (Picea glauca) seed, the megagametophyte, undergoes programmed cell death (PCD). Protease activities in megagametophyte cells that arise post-germinatively were investigated. The accumulation of protease activities

Rarobacter faecitabidus protease I (RPI) is a serine protease exhibiting lytic activity toward living yeast cells. RPI is similar to elastase in its substrate specificity and has a lectin-like affinity for mannose. The gene encoding RPI was cloned to elucidate its structure and function. And its

Toxoplasma gondii is a parasite of great medical and veterinary importance that has worldwide distribution and causes toxoplasmosis. There are few treatments available for toxoplasmosis and the search for plant extracts and compounds with anti-Toxoplasma activity is of utmost importance for the

A putative citrus vacuolar processing thiolprotease cDNA (Cit-vac) was isolated from a cDNA library of Citrus fruits (Citrus sinensis L. Osbeck var Washington navel). The cDNA is 58 and 57% identical with vacuolar processing seed proteases from castor bean and soybean, respectively. The Citvac

Hemostasis is a tightly regulated process which maintains a fluid state of blood within the vasculature and provides thrombotic response upon tissue injury. Various scientific studies have implicated the role of plant latex proteases in hemostasis using in vitro experiments. However, in vivo models

Deoiled Jatropha seed cake was assessed for its suitability as substrate for enzyme production by solid-state fermentation (SSF). Solvent tolerant Pseudomonas aeruginosa PseA strain previously reported by us was used for fermentation. The seed cake supported good bacterial growth and enzyme

The nucellus is a complex maternal grain tissue that embeds and feeds the developing cereal endosperm and embryo. Differential screening of a barley (Hordeum vulgare) cDNA library from 5-d-old ovaries resulted in the isolation of two cDNA clones encoding nucellus-specific homologs of the

Papain-like cysteine proteases (PLCPs) are a class of proteolytic enzymes involved in many plant processes. Compared with the extensive research in Arabidopsis thaliana, little is known in castor bean (Ricinus communis) and physic nut (Jatropha curcas), two Euphorbiaceous plants without any recent

A proteolytic enzyme, curcain, has been extracted from the latex of Jatropha curcas Linn. The enzyme was purified by chromatography on carboxymethyl cellulose and gel filtration on Sephadex G-200. The homogeneity of protein associated with curcain was established by non-denatured polyacrylamide gel

Both ricin and R. communisagglutinin (RCA120), belonging to the type II ribosome-inactivating proteins (RIPs-Ⅱ), are derived from the seeds of the castor bean plant. They share very similar amino acid sequences, but ricin is much more toxic than RCA120. It is urgently necessary to

This study focused on the solid-state fermentation of Jatropha seed cake (JSC), a byproduct generated after biodiesel production. Presence of anti-nutritional compounds and toxins restricts its application in livestock feed. The disposal of the JSC is a major environmental problem in the future, due
