Publication number: 20250092102Abstract: The present invention provides a transcription factor NCgl0581 mutant and use thereof in L-serine detection, belonging to the technical field of biological detection. According to the present invention, key binding sites of the transcription factor NCgl0581 with L-serine are obtained through molecular docking, and further model analysis and virtual screening are carried out to obtain an L-serine biosensor mutant NCgl0581E136P. Experiments show that the biosensor constructed based on the mutant NCgl0581E136P can respond to 25 mM serine, which is half of the response concentration before the mutation. The present invention reduces the detection limit of the biosensor through mutation, lays a foundation for the detection of low-concentration L-serine, and has good application value and prospect.Type: ApplicationFiled: November 24, 2024Publication date: March 20, 2025Inventors: Xiaomei ZHANG, Yamin Huang, Yujie Gao, Guoqiang Xu, Hui Li, Jinsong Shi, Zhenghong Xu

Patent number: 12250149Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.Type: GrantFiled: May 10, 2022Date of Patent: March 11, 2025Assignee: Tencent Technology (Shenzhen) Company LimitedInventors: Maocai Li, Zongyou Wang, Jinsong Zhang, Huankun Huang, Kaiban Zhou, Yifang Shi, Qucheng Liu, Pan Liu, Hu Lan, Changqing Yang, Gengliang Zhu, Li Kong
