Abstract: A transaminase mutant and use hereof, the amino acid sequence of the transaminase mutant is an amino acid sequence in which the amino acid sequence as represented by SEQ ID NO: 1 is mutated, the mutated amino acid position being one or more selected from among F89, K193, P243, V234, I262, Q280, V379, R416, A417 and C418. The enzymatic activity and/or stability of the transaminase mutant is improved.

Abstract: The present invention discloses a data stream distribution method and apparatus. In the method, a load balancer may access data in a data stream according to an instruction in a distribution rule that is sent by an application server according to an interface protocol or configured on the load balancer according to an interface protocol; determine, according to a keyword generated according to the accessed data, an application server that processes the data stream; and send the data stream to the determined application server. Therefore, the load balancer may access the data in the data stream according to an instruction in a common distribution rule, to distribute the data stream, thereby reducing complexity of data stream distribution performed by the load balancer.

Abstract: This application provides a data processing method and apparatus. The method includes: receiving, by a first VNFC a first data packet and a flow label of the first data packet that are sent by a second VNFC, where the flow label is generated by the second VNFC according to flow information of the first data packet or is received by the second VNFC from a third VNFC; and selecting, by the first VNFC according to the flow label, a first processing node configured to process the first data packet, where the first processing node is a processing node in the first VNFC. By means of the method in this application, system consumption can be reduced, and processing efficiency of a data packet can be improved.

Abstract: Transmitting audio and video signals, can include: detecting if the state of a video control signal has changed, where a video signal includes the video control signal and a video data signal; generating, if the state of the video control signal has not changed, a first serial data packet based on the video signal and an audio signal; generating, if the state of the video control signal has changed, a second serial data packet based on the video signal and the audio signal; transmitting over a serial link, an encoded data frame formed by encoding the first and second serial data packets in a predetermined encoding manner; decoding and de-serializing the encoded data frame to restore the video signal and the audio signal; and outputting the video signal to a video display circuit, and outputting the audio signal to an audio processor respectively.
