Patent number: 6326470Abstract: Plant cell expansion is regulated by wall relaxation and yielding, which is thought to be catalyzed by elusive “wall loosening” enzymes. By employing a reconstitution approach, we initially found that a crude protein extract from the cell walls of growing cucumber seedlings possessed the ability to induce the extension of isolated cell walls. This activity was restricted to the growing region of the stem and could induce the extension of isolated cell walls from various dicots and monocots, but was less effective on grass coleoptile walls. Sequential HPLC fractionation of the active wall extract revealed two proteins with molecular masses of 29 and 30 kD, as measured by SDS-PAGE, associated with such activity. Each protein, by itself, could induce wall extension without detectable hydrolytic breakdown of the wall. We proposed the name “expansins” for this class of proteins.Type: GrantFiled: October 28, 1999Date of Patent: December 4, 2001Assignee: The Penn State Research FoundationInventor: Daniel J. Cosgrove

Patent number: 5731419Abstract: The present invention relates to three novel genes which have been isolated from cold-tolerant wheat species and which are induced by low temperature. The first gene, Wcs19, is preferentially expressed in green leaf tissues of tolerant gramineae species and requires both light and low temperature for maximal induction. The second gene, Wcs120, is induced only by low temperature. Different from the protein encoded by Wcs19, the protein encoded by Wcs120 contains two repeated domains that are highly conserved among RAB (rice abscisic acid-induced) and dehydrin families and appears to be light-independent. The Wcs120 protein does not however contain a serine-rich sequence present in RAB and dehydrin families. Finally, the present invention also relates to a third gene, Wcor410, also induced by low temperature as well as water stress and, to a lesser extend, by ABA. Its expression is light-independent. The protein encoded by this gene contains a serine-rich stretch as found in several drought induced proteins.Type: GrantFiled: August 16, 1993Date of Patent: March 24, 1998Assignee: Universite du Quebec a MontrealInventors: Fathey Sarhan, Mario Houde, Jean-Francois Laliberte

The complexes can be used for the treatment of ulcers, inflammations or viral infections, or as immunostimulant.Type: GrantFiled: August 18, 1986Date of Patent: August 8, 1989Assignee: Intex Pharmazeutische Produkte AGInventor: Gabriel Emoedi

Patent number: 4806626Abstract: New .alpha.-amylase inhibitor from wheat (WAI-53). The inhibitor is characterized especially by having molecular weight of 24,000 as determined by gel filtration, giving a single band at an electrophoretic mobility of 0.53 on polyacrylamide gel electrophoresis according to the Davis Disc Electrophoresis Method and producing saturation curves of WAI-53 with human salivary alpha-amylase and with human pancreatic alpha-amylase with a ratio of the amount of WAI-53 required to produce 50% inhibition of human salivary .alpha.-amylase to that of human pancreatic amylase above 1:250. The alpha-amylase inhibitor is used for quantitative analysis of alpha-amylase isozymes in body fluid.Type: GrantFiled: June 15, 1987Date of Patent: February 21, 1989Assignees: Nisshin Flour Milling Co., Ltd., Oriental Yeast Co., Ltd.Inventors: Koji Maeda, Osamu Oka

Patent number: 4771126Abstract: A method for fraction fractionation of a vegetable protein such as soybean protein which comprises subjecting a source of the vegetable protein in an aqueous system to reduction conditions such as treatment with a sulfite compound, a glutathione compound or cysteine compound, or electrolytic reduction at pH within a neutral or alkaline range and then bringing the system to pH of 5.5 to 7.0 at a temperature of 20.degree. C. or lower to fractionate the system into a soluble or dispersing fraction and an insoluble or precipitate fraction.Type: GrantFiled: June 19, 1987Date of Patent: September 13, 1988Assignee: Fuji Oil Company, Ltd.Inventors: Motohiko Hirotsuka, Masahiko Terashima, Hitoshi Taniguchi

Patent number: 4716218Abstract: A process for the production of grain oil, dehydrated alcohol, grain protein and starch, is disclosed. The invention comprises the steps of (a) drying cracked grain, (b) leaching the dried grain with an ethanol solution of 90 to 100% w/v ethanol and recovering dehydrated alcohol and grain oil, (c) extracting the residue of step (b) with a second ethanol solution containing NaOH and recovering food grade protein, and (d) separating starch and fiber from the residue of step (c) by starch hydrolysis or by grinding the residue and separating the starch and fiber by a screen and/or centrifuge.Type: GrantFiled: January 15, 1986Date of Patent: December 29, 1987Assignee: Purdue Research FoundationInventors: Li-Fu Chen, Johan E. Hoff

Patent number: 4689409Abstract: A process for the production of starch and gluten from wheat flour or similar flour. The flour is extracted with water so as to produce a starch fraction and a gluten fraction. A `B` starch is then separated from either the starch fraction or the gluten fraction and contacted with an aqueous alkali at a pH between 8.5 and 12.5 to give a starch suitable for conversion to starch hydrolyzates by enzymatic hydrolysis.Type: GrantFiled: March 3, 1986Date of Patent: August 25, 1987Assignee: CPC International Inc.Inventors: Alan L. Reeve, Henry H. Nonaka
