According to the invention, the target protein can be secreted into cell culture broth in a pure form without fusion with other proteins so that the efficient isolation and purification of the target protein is possible.Type: GrantFiled: July 15, 2005Date of Patent: May 31, 2011Assignee: Korea Advanced Institute of Science and TechnologyInventors: Sang Yup Lee, Jong Hyun Choi

Patent number: 7951559Abstract: The invention relates to the recombinant expression of a peptide of interest in the form of a fusion protein comprising a solubility tag. The fusion protein comprises at least two portions separated by a cleavable peptide sequence wherein one portion is devoid of cysteine residues and the second portion comprises an effective number of cross-linkable cysteine residues. After cell lysis and isolation of the fusion protein, the fusion protein is subsequently cleaved into a mixture of first and second portions. Oxidative cross-linking is used to selectively precipitate one of the two portions to facilitate simple and effective separation of the peptide of interest.Type: GrantFiled: July 14, 2008Date of Patent: May 31, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Albert W. Alsop, Qiong Cheng, Linda Jane Solomon, Stephen R. Fahnestock, Tanja Maria Gruber, Pierre E. Rouviere

Patent number: 7951561Abstract: Halophilic marine gram negative bacteria, isolated from decayed algae, hydrolyzed ?-carrageenan. To maximize ?-carrageenase production in the cost effective manner, a novel medium was defined having minimum components and their optimum concentration by statistical optimization method. Hence there evolved a novel medium composition for enhanced ?-carrageenase production by a new halotolerant marine bacterium, Pseudomonas spp.Type: GrantFiled: August 25, 2006Date of Patent: May 31, 2011Assignee: Council of Scientific and Industrial ResearchInventors: Yasmin Najmuddin Khambhaty, Kalpana Haresh Mody, Bhavanath Jha

Patent number: 7951562Abstract: This invention relates to a multifunctional enzyme having lysyl hydroxylase and glycosyltransferase activity and to the use of the enzyme in glycosylating hydroxylysine residues. In particular this invention relates to a method for producing glycosyltransferase activity, which comprises that a nucleotide sequence encoding lysyl hydroxylase and glycosyltransferase activity is introduced and expressed in a chosen host and the protein product is recovered from the host cell or from the culture medium.Type: GrantFiled: October 31, 2007Date of Patent: May 31, 2011Assignee: Oulun YliopistoInventors: Raili Myllyla, Jari Heikkinen, Maija Risteli, Chunguang Wang
