Patent number: 7183098Abstract: Loline alkaloids (LA), which are 1-aminopyrrolizidines with an oxygen bridge, are produced by Epichloë (anamorph=Neotyphodium) species, endophytes of grasses. LA are insecticidal, thus helping protect host plants from insect herbivory. Suppression subtractive hybridization PCR was used to isolate transcripts up-regulated during loline alkaloid production in cultures of Neotyphodium uncinatum. Subtracted cDNAs were cloned, and a ?-phage cDNA library from an LA-expressing N. uncinatum culture was screened with subtracted cDNA. In BLAST searches, several cDNAs identified had sequence similarities to aspartate kinases, and another with O-acetylhomoserine-(thiol)lyase. Differential expression of these two genes in LA-producing cultures of N. uncinatum was confirmed, and in a survey of 23 isolates from 21 Neotyphodium and Epichloë species these two genes strictly correlated with LA production. Two nucleic acid molecules encoding two loline alkaloid gene clusters have been identified.Type: GrantFiled: June 24, 2003Date of Patent: February 27, 2007Assignee: University of Kentucky Research FoundationInventors: Christopher L. Schardl, Heather H. Wilkinson, Martin J. Spiering

Patent number: 7105330Abstract: The invention is based on the discovery of methods for purification of an acid active hyaluronidase found in human plasma (hpHAse), including both biochemical and immunoaffinity purification methods. The method of immunoaffinity purification of the invention is based on the discovery of a method for identifying antibodies that specifically bind native hpHAse (anti-native hpHAse antibodies), and anti-native hpHAse antibodies identified by this screening method. The invention also features an assay for sensitive detection of HAse activity using biotinylated hyaluronic acid (bHA). Purification and characterization of hpHAse lead to the inventors' additional discovery that hpHAse is encoded by the LuCa-1 gene, which gene is present in the human chromosome at 3p21.3, a region associated with tumor suppression. The invention additionally features methods of treating tumor-bearing patients by administration of hpHAse and/or transformation of cells with hpHAse-encoding DNA.Type: GrantFiled: July 18, 2003Date of Patent: September 12, 2006Assignee: The Regents of the University of CaliforniaInventors: Robert Stern, Gregory I.

Patent number: 7083962Abstract: An objective of the present invention is to provide methods for efficiently producing (S)-1-(3,4-dimethoxyphenyl)-2-propanol at a high optical purity. Another objective is to provide novel reductases which reduce 3,4-dimethoxyphenylacetone, using NADPH as a coenzyme, to produce (S)-1-(3,4-dimethoxyphenyl)-2-propanol with a high optical purity. The inventors found that a 3,4-dimethoxyphenylacetone-reducing enzyme present in Torulaspora delbrueckii is a novel carbonyl reductase that reduces various carbonyls. This novel enzyme reduces 3,4-dimethoxyphenylacetone in a reduction reaction to produce (S)-1-(3,4-dimethoxyphenyl)-2-propanol with a high optical purity and at a high yield. Furthermore, the inventors isolated a DNA that encodes the present enzyme, and generated a recombinant bacterium which highly expresses the present enzyme. Thus, the present inventors established a simple and highly economical method of obtaining optically active alcohols with a high optical purity and at a high yield.Type: GrantFiled: April 15, 2004Date of Patent: August 1, 2006Assignee: Daicel Chemical Industries Ltd.Inventors: Norihiro Kimoto, Hiroaki Yamamoto, Takanori Nakajima
