The invention discloses a general simulation system suitable for a data processing FPGA (Field Programmable Gate Array). The general simulation system comprises a simulation SDRAM (Synchronous Dynamic Random Access Memory) module, a simulation storage board module, a simulation transmitter preceding stage module, a simulation load input module and a simulation clock/reset module. The simulated SDRAM module is used for caching load data received by the data processing system; the simulated storage board module is used for storing data; the imitation transmitter preceding stage module is used for receiving, descrambling, unpacking and storing various kinds of load data in a classified manner; the simulated load input module is used for providing load data for the data processing system; and the imitated clock/reset module is used for providing clock and reset signals for working for the system. The method is suitable for FPGA simulation verification of data processing of a common data transmission ...

The invention relates to a Trichoderma reesei CBHI signal peptide mutant and application of the Trichoderma reesei CBHI signal peptide mutant in promoting high-efficiency expression and secretion of heterologous protein. The amino acid sequence of the Trichoderma reesei CBHI signal peptide mutant SPM1 is as shown in SEQ ID NO.1, and the nucleotide sequence of the Trichoderma reesei CBHI signal peptide mutant SPM1 is as shown in SEQ ID NO.2. The Trichoderma reesei CBHI signal peptide mutant SPM1 is obtained by adding two leucines behind the fourth lysine of the Trichoderma reesei CBHI signal peptide on the basis of the Trichoderma reesei CBHI signal peptide. According to the mutant, the guiding capability on the heterologous protein is enhanced, and the expression and secretion of the heterologous protein XynST11 can be effectively promoted. After the Trichoderma reesei CBHI signal peptide mutant SPM1 is introduced in the expression and secretion process of the heterologous protein XynST11 ...

The invention relates to a Trichoderma reesei transcription activator Xyr1 mutant and application of the Trichoderma reesei transcription activator Xyr1 mutant in increasing the yield of cellulase and xylanase. Wherein the amino acid sequence of the Trichoderma reesei transcription activator mutant Xyr1R434L is as shown in SEQ ID NO.3, and the nucleotide sequence of the Trichoderma reesei transcription activator mutant Xyr1R434L is as shown in SEQ ID NO.4. According to the Trichoderma reesei transcription activator mutant Xyr1R434L, based on Trichoderma reesei Xyr1, arginine at the 434th site is mutated into leucine, and the Trichoderma reesei transcription activator mutant Xyr1R434L is obtained. The mutant improves the transcriptional activation capability of Xyr1, and can effectively promote the expression and secretion of trichoderma reesei cellulase and xylanase. After the mutant Xyr1R434L is overexpressed, the enzyme activity of cellulase and the enzyme activity of xylanase in fermentation ...

The invention relates to a method for increasing the yield of xylanase in trichoderma reesei. According to the invention, a trichoderma reesei endogenous protein Xyn2 is used as a fusion expression element, the fusion expression element Xyn2 and a coding gene of xylanase Xyn10A are connected together to form a fusion protein gene, then the fusion protein is subjected to heterologous expression, and xylanase is synthesized. The nucleotide sequence of the fusion expression element Xyn2 is as shown in SEQ ID NO.2, and the amino acid sequence of the fusion expression element Xyn2 is as shown in SEQ ID NO.1. The enzyme activity of the xylanase obtained by the method is obviously higher than that of the xylanase Xyn10A which is directly expressed, the enzyme activity of the xylanase produced by the recombinant trichoderma reesei xyn2-xyn10A by taking glucose as a carbon source reaches 170U/mL, and the enzyme activity of the xylanase produced by the strain by taking cellulose as a carbon source ...
