Patent number: 10196627Abstract: The present invention relates to a novel carbon dioxide fixation cycle synthesizing a carbohydrate product from carbon dioxide in vitro. In addition, the present invention relates to a unit or a composition carrying out carbon dioxide fixation in cyclic manner. Additionally, the present invention relates to a method to fix carbon dioxide or a method to produce glyoxylate from the carbon dioxide fixation cycle. The present carbon dioxide fixation cycle is not found in natural world, and we found that, when the novel carbon dioxide fixation cycle is used, only three ATP molecules are consumed to fix one carbon dioxide molecule, and thus novel carbon dioxide fixation cycle has an energy conversion efficiency approximately 2.5 times higher than that of the Calvin cycle.Type: GrantFiled: February 24, 2015Date of Patent: February 5, 2019Assignee: Sogang University Research FoundationInventors: Jeong Kug Lee, Eui Jin Kim, Kyu Ho Lee

Patent number: 9963722Abstract: A bacterial strain secreting fatty acids, the strain inducing fatty acids to be extracellularly secreted by using phospholipase expressed in the periplasmic space of cell. When a method of producing fatty acids by using the bacterial strain secreting fatty acids is used, fatty acids extracellularly secreted are continuously obtained without apoptosis, leading to lower costs and higher production efficiency. Phospholipase, unlike thioesterase, which is a typical fatty-acid degrading enzyme, decomposes phospholipid to produce free fatty acids. Accordingly, by using the substrate specificity of two different phospholipases, a fatty acid having a specific composition can be selectively produced. Unlike in a typical method in which fat is obtained from cells or tissues, fatty acids secreted during cell growth are obtainable by biding to a hydrophobic material without an extraction process using an organic solvent in large quantities.Type: GrantFiled: June 3, 2015Date of Patent: May 8, 2018Assignee: SOGANG UNIVERSITY RESEARCH FOUNDATIONInventors: Jeong Kug Lee, Eui Jin Kim, Xiaomeng Tong, Eun Kyung Oh

Patent number: 9816118Abstract: A method of continuously producing 5-aminolevulinic acid employs the photosynthetic bacteria-derived photosynthetic membrane vesicle, succinyl-CoA synthetase, and 5-aminolevulinic acid synthase. The enzymatic synthesis of 5-aminolevulinic acid directly from succinic acid and glycine may be simple, but the synthesis is not inexpensive due to the supply of ATP and CoA, which are relatively expensive reactants. The photosynthetic membrane vesicle is used together with succinyl-CoA synthetase and 5-aminolevulinic acid synthase, thereby enabling the re-use of adenosine diphosphate or CoA in reaction. Accordingly, relatively expensive 5-aminolevulinic acid can be efficiently produced at low manufacturing costs from succinic acid and glycine.Type: GrantFiled: November 4, 2015Date of Patent: November 14, 2017Assignee: SOGANG UNIVERSITY RESEARCH FOUNDATIONInventors: Jeong Kug Lee, Hyeon Jun Kim, Eui Jin Kim
