ipomoea cairica/protease

Carnein is an 80 kDa subtilisin-like serine protease from the latex of the plant Ipomoea carnea which displays an exceptional resistance to chemical and thermal denaturation. In order to obtain the first crystal structure of a plant subtilisin and to gain insight into the structural determinants

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

A new serine protease from the latex of Ipomoea carnea spp. fistulosa (Morning glory), belonging to the Convolvulaceae family, was purified to homogeneity by ammonium sulfate fractionation followed by cation exchange chromatography. The enzyme, named carnein, has a molecular mass of 80.24 kDa

Angiotensin converting enzyme 2 (ACE2) and main protease (M^Pro) are significant target proteins, mainly involved in the attachment of viral genome to host cells and aid in replication of severe acute respiratory syndrome-coronaviruses or SARS-CoV genome. In the present study, we

Granulins are a family of evolutionarily ancient proteins that are involved in regulating cell growth and division in animals. In this report a full-length cDNA, SPCP3, was isolated from senescent leaves of sweet potato (Ipomoea batatas). SPCP3 contains 1389 nucleotides (462 amino acids) in its open

Different parasites cause severe lose in quantity and quality of crops. Many parasites develop haustorial cells and stylets that penetrate the host using secreted enzymes and mechanical pressure. Cysteine proteases are pre-pro-enzyme produced by parasites that are essential for normal parasitism.

Glutaredoxins (Grx) play an important role in reduction of protein glutathione mixed disulphides. An IbGrx cDNA (561 bp, EF362614) encoding a putative dithiol Grx was cloned from sweet potato (Ipomoea batatas [L.] Lam). The deduced amino acid sequence is conserved among the reported dithiol Grx,

We isolated several senescence-associated genes (SAGs) from the petals of morning glory (Ipomoea nil) flowers, with the aim of furthering our understanding of programmed cell death. Samples were taken from the closed bud stage to advanced visible senescence. Actinomycin D, an inhibitor of

An endo-beta-mannanase (EC 3.2.1.78) from Streptomyces ipomoea CECT 3341 was purified and applied to the biobleaching of pine kraft pulps. The maximum level of endo-beta-mannanase activity (0.6 units ml(-1)) was achieved after 4 days of growth in a medium containing locust bean gum and yeast

Sporamin accounts for about 60% to 80% of total soluble protein in sweet potato tubers, and the predicted protein sequence of sporamin shares significant amino acid sequence identity with some Kunitz-type trypsin inhibitors. We constructed three recombinant plasmids with cDNAs that encode

Plants perceive and respond to volatile signals in their environment. Herbivore-infested plants release volatile organic compounds (VOCs) which can initiate systemic defense reactions within the plant and contribute to plant-plant communication. Here, for Ipomoea batatas (sweet potato) leaves we
