The present invention relates generally to proteinase inhibitors, a precursor thereof and to genetic sequences encoding same. More particularly, the present invention relates to a nucleic acid molecule comprising a sequence of nucleotides which encodes or is complementary to a sequence which encodes a type II serin proteinase inhibitor (PI) precursor from a plant wherein the precursor comprises at least three PI monomers and wherein at least one of the monomers has a chymotrypsin specific site and at least one other of the monomers has a trypsin specific site.

Proteinase inhibitor, precursor thereof and genetic sequences encoding same

The present invention relates generally to proteinase inhibitors, a precursor thereof and to genetic sequences encoding same. More particularly, the present invention relates to isolated monomers of a type II serine proteinase inhibitor.

Certain cultured plant cell gums, including those produced in suspension culture of plant cells of plants of the family Aizoaceae are described. Plant cell gums of plants of the genus Mesembryanthemum are specifically provided. Also described are the methods of using these cultured plant cell gums in the manufacture of food products, pharmaceuticals and veterinary products, cosmetics and other industrial products, such as paper, adhesive, ink, textiles, paint, ceramics, explosives, cleaning agents or detergents, products for firefighting, agricultural chemicals including pesticides and fungicides, for oil and gas production, and in photography, lithography, and other industries are described. Food, pharmaceutical, veterinary, industrial and cosmetic compositions containing certain cultured plant cell gums are also described. Plant cell gums can be employed as substitutes for plant exudate and extract gums and other known emulsifying, viscosifying and gelling agents.

Cultured plant cell gums for food, pharmaceutical, cosmetic and industrial applications

Proteinase inhibitor, precursor thereof and genetic sequences encoding

This invention provides plant arabinogalactan proteins (AGPs) and their genes. AGPs were isolated from Nicotiana alata, Nicotiana plumbaginafolia, and Pyrus communis. Amino acid sequences of isolated AGP peptide fragments are presented. Isolated AGP fragments were used to synthesize oligonucleotide probes to prepare oligonucleotide primers for PCR or prepare RNA probes to screen cDNA libraries of N. alata, N. plumbaginafolia, and P. communis. cDNA clones encoding amino acid sequences of isolated AGP fragments were isolated. The invention presents for the first time an intact AGP amino acid sequence derived from a corresponding AGP gene. The instant invention further provides methods useful in obtaining AGP genes encoding an AGP peptide comprising a specific isolated hydroxyproline-rich (OAST-rich) sequence or a specific isolated hydroxyproline-poor sequence.

Methods of using cultured plant cell gums in the paper, adhesive, oil and gas, ink, lithography, textile, paint, ceramics, cleaning detergent, cosmetics, photography, explosive, firefighting, agricultural, and other industries are described. Industrial and cosmetic compositions containing cultured plant cell gums are also described.

Industrial pharmaceutical and cosmetics applications for cultured plant

A method for the culturing of gum-secreting plant cells, recovery of the gum from the medium and use of the plant gum in food products is described. In particular, the plant gum product of cultured Pyrus, Prunus avium and Rosa cells can be used in food products as comprising complex carbohydrates and glycoproteins, for example, an emulsifying agent, an emulsion stabilizer, a thickening agent or a texture modifier.
