Description

Metallothionein gene MT18, metallothionein obtained by encoding metallothionein gene MT18, expression and application of metallothionein
Technical Field
The invention belongs to the technical field of genetic engineering, and particularly relates to a metallothionein gene, metallothionein obtained by encoding the metallothionein gene, and expression and application of the metallothionein gene.
Background
Metallothionein (MT) is a metal binding protein commonly existing in organisms. Metallothioneins are low molecular weight proteins with metal binding capacity and high induction properties. The cysteine-rich short peptide has high affinity to various heavy metals. It is a protein with low molecular mass and extremely high cysteine residue and metal content. The metals bound thereto are mainly cadmium, copper and zinc, widely present in various organisms from microorganisms to humans, and the structures thereof are highly conserved.
Heavy metal bioremediation is a technology for heavy metal treatment by using biological materials, and heavy metal resistance genes are important resources for bioremediation. The biological material based on gene modification can break through the character limitation of natural biological materials, obtain the optimized combination of biomass, growth speed and repair efficiency, and the heavy metal resistance gene from microorganisms has shown great potential in the aspect of development of high-efficiency repair biological materials. As early as 1998, Nature Biotechnology (Rugh et al, 1998) reported that Populus tremula (yellow poplar, also known as Liriodendron tulipifera) stably expresses the bacterial mercury reducing gene merA, and that this transgenic plant exhibits an eco-friendly plant repair pathway. Arsenic methylation gene arsM from Rhodopseudomonas palustris (Rhodopseudomonas palustris) has recently been used to construct genetically engineered bacteria that demonstrate the potential for efficient remediation of arsenic contaminated soil (Chen et al, 2014). A few studies have also shown the potential of genetically engineered biomaterials in cadmium contamination remediation. For example, Shim et al transferred the yeast cadmium resistance gene YCF1 into poplar, promoted the growth of the plant in cadmium contaminated soil, and also enhanced the cadmium enrichment capacity of the plant (Shim et al, 2013); kang et al transferred three microbial cadmium resistance genes SpPCS, GshI and MntA into Escherichia coli, so that the cadmium enrichment capacity of the transgenic strain was increased by 25 times (Kang et al, 2007).
At the present stage, the metallothionein source with heavy metal tolerance/enrichment effect is usually from animals and plants, and the metallothionein source from microorganisms is rarely researched.

EXAMPLE III
Detailed procedure of function verification.
9.2 Minimum Inhibitory Concentration (MIC), the MIC value of Cd was assessed by measuring the ability of bacterial cells to grow in medium at different Cd concentrations. First, MT18 containing the transformed strain and its corresponding blank (empty pET28a (+)) were grown on Lauria Bertani (LB) -agar plates overnight at 29 ℃. Then, the recombinant plasmids containing bacterial colonies were spread onto LB-plate plates containing various concentrations (0-16mM) of Cd, including kanamycin (50mg/L), and an inducer (IPTG-isopopyl-B-D-1-thiogalactopyranoside, 100 mg/L). ) Their MICs were determined.
Determining a blank control Escherichia coli (e.coli) BL21(DE3) and Cd minimum inhibitory concentration, and determining said Escherichia coli BL21(DE3) by DropAssay; referring to FIG. 1, the blank E.coli (E.coli) BL21(DE3) labeled as pET28a was not viable at a Cd concentration of 1.0mmol/L and its minimum inhibitory concentration was Cd1.0 mmol/L; the transformed strain, the reference number of which is MT18, can survive when the concentration of Cd is 1.1mmol/L and 1.2mmol/L, and the minimum inhibition concentration of Cd is 1.3mmol/L proves that the transformed strain has good cadmium tolerance.
9.3 growth patterns (growth curves) for the more tolerant strains in different Cd solutions were screened.
For this assay, first, the stored bacterial cells were transferred to LB-agar plates containing kanamycin and IPTG and incubated overnight at 37 ℃ for activation. Then, individual bacterial colonies were transferred to 100mL LB liquid medium containing the antibiotics kanamycin (50. mu.g/mL), IPTG (100. mu.g/mL) and 1.0mM Cd. The bacterial samples were continuously shaken at 37 deg.C, 160 ℃ and 180 rpm. After 12-14 hours of shaking, bacterial samples were examined every 1 hour for absorbance at 600nm (optical density OD600) for 24 hours by a nanodrop spectrophotometer. All readings were plotted in FIG. 2 to obtain a growth curve for each bacterium in 1.0mM Cd.
As shown in fig. 2, PET 1-PET 3 are blank control Escherichia coli BL21(DE3), the transformed strain is labeled MT18 in the figure, during the growth process, the absorbance (number of colonies) of the transformed strain is higher than that of three blank control Escherichia coli samples, and the transformed strain maintains higher growth, reaches the highest peak in 15 th hour, the number of colonies of the transformed strain is 20% higher than that of the blank control Escherichia coli, and the Cd tolerance performance and the lifetime are proved to be good under the Cd environment.

In the tube. Biomass was digested by using nitric acid (65% strength) overnight. After complete digestion, heat is applied to remove the liquid. Then 2ml of 3% nitric acid was added to each tube. After 14-16 hours, the solution was filtered and transferred to a clean and dry tube. After completion of the acid digestion, the cadmium concentration in all samples was determined using an atomic absorption spectrophotometer (TAS-990). By detecting that the cadmium adsorption value of a blank control escherichia coli sample is 93.63g/kg, the cadmium adsorption value of the transformation strain is 119.64g/kg, and the cadmium adsorption capacity of the transformation strain is stronger than that of the blank control escherichia coli sample.
