The invention discloses a bacillus subtilis self-induced gene expression system based on a two-component quorum sensing element, and belongs to the technical field of gene engineering. A lasting and high-expression self-induced gene expression system is developed. The invention provides an expression system of a self-induced gene. The expression element is composed of a constitutive promoter, a target promoter, an RBS sequence of an agrA gene and/or an RBS sequence of an agrD gene, a gene agrA for coding response regulatory protein, a gene agrD for coding a signal molecule AIP precursor, a gene agrB for coding signal processing protein and a gene agrC for coding sensing protein which is combined with the signal molecule and starts signal conduction. The invention provides a new thought and method for designing a recombinant protein expression system based on bacillus subtilis.

The utility model discloses a split type network transformer structure, which relates to the technical field of transformers and comprises a second box body, a second pin is fixedly connected to the bottom of the second box body, the second box body is clamped in a first box body, a first pin is fixedly connected to the upper surface of the first box body, and a second pin is fixedly connected to the lower surface of the second box body. And the first box body is fixedly connected with a transformer shell. According to the utility model, the first pins are arranged on the first box body and the second pins are arranged on the second box body, so that the first box body is clamped with the second box body, the first pins are in contact with the second pins, and the original mode that the split network transformer is directly welded on the circuit board through the pins is changed into the clamping mode. The split type network transformer solves the problems that a special tool is needed ...
