Publication number: 20240124853Abstract: Provided are transaminase mutants and uses thereof. The transaminase mutant is obtained by one or more amino acid mutations occurring in SEQ ID NO: 2 or is a mutant with a conserved amino acid mutation obtained by taking the sequence SEQ ID NO: 1 of a wild-type CvTA transaminase as a reference. Compared with wild-type transaminases, the catalytic activity of the mutant is improved to different degrees, so that the production efficiency of chiral amine compound synthesis may be improved.Type: ApplicationFiled: July 6, 2021Publication date: April 18, 2024Inventors: Hao Hong, Gage James, Yi Xiao, Na Zhang, Xuecheng Jiao, Yulei Ma, Huiyan Mou, Zujian Wang, Kaihua Sun, Xiang Li, Tong Zhao, Shan Cao

Publication number: 20240117395Abstract: Provided is a method for synthesizing a chiral amine compound. A transaminase is used to transaminate a ketone substrate under the action of an amino donor, to obtain the chiral amine compound; and the conserved amino acid sequence region of the transaminase at least includes a region 1 (MAGLWCVN) and a region 2 (YNTFFKT). With the transaminase with the specific conserved amino acid sequence region to synthesize a large sterically hindered chiral amine, the enzyme catalytic reaction volume is small, the synthesizing route is short, the product yield is high, a high-cost noble metal is not required for catalysis under the synthesizing conditions, three wastes are reduced, and the production cost is saved.Type: ApplicationFiled: July 6, 2021Publication date: April 11, 2024Inventors: Hao Hong, Gage James, Yi Xiao, Na Zhang, Xuecheng Jiao, Yulei Ma, Huiyan Mou, Zujian Wang, Kaihua Sun, Ru Jia, Fang Liu, Wenjing Liu

Publication number: 20230144763Abstract: Systems and methods are disclosed herein for improved per-frequency counting systems that record interactions between individuals and a group of providers while maintaining differential privacy. A protocol may be defined that specifies frequency bins to categorize identifiers corresponding to individuals. A provider may generate a plurality of private sketches, each corresponding to a plurality of frequencies defined in the protocol. Frequency data is determined for each identifier. Identifiers are encoded into the private sketches corresponding to the identifiers’ associated frequency. The plurality of private sketches from each provider in the group of providers are combined to generate a deduplicated distribution across the group. In one implementation, the private sketches of each provider are sequentially merged until all sketches have been combined, from which the total distribution can be estimated.Type: ApplicationFiled: June 23, 2021Publication date: May 11, 2023Inventors: Jiayu Peng, Sheng Na Ma, Xichen Huang, James Robert Koehler, Lu Zhang
