Abstract: An engineered type V Cas protein is provided, including a parental type V Cas protein and an HNH domain. The HNH domain is located at an N-terminus of the parental type V Cas protein; or the HNH domain is located between two continuous or non-continuous amino acids of the parental type V Cas protein, named as a first amino acid and a second amino acid, respectively. The first amino acid and the second amino acid are selected from one of amino acids 1 to 10 at the N-terminus of the parental type V Cas protein, and the first amino acid and the second amino acid are different amino acid positions of the parental type V Cas protein; or the first amino acid and the second amino acid are selected from amino acid positions corresponding to amino acids 794 and 795 of SEQ ID NO: 9.

Abstract: This application provides a wireless charging transmitting apparatus, a wireless charging receiving apparatus, and a system thereof. The wireless charging transmitting apparatus includes an inverter circuit, a first transmitting plate, and a second transmitting plate. The wireless charging receiving apparatus includes a first receiving plate, a second receiving plate, and a rectifier circuit. An input end of the inverter circuit is connected to a direct current power supply, a first output end of the inverter circuit is connected to the first transmitting plate, and a second output end of the inverter circuit is connected to the second transmitting plate. A first contact is disposed on the first transmitting plate, and a second contact is disposed on the first receiving plate. When the first contact is in contact with the second contact, the first transmitting plate establishes an electrical connection to the first receiving plate.
