The organic compounds from biochar play a role of hormone analogs, stimulating the expression of metabolites by controlling related gene and protein. In this experiment, we reported the L-histidine biosysthesis was promoted by biochar treatment in unlike genetic engineering of the traditional method. The related results indicated the most optimal concentration was found to be 3%, and 7% is the lethal dose. was inhibited in the high-concentration treatment. On the other hand, docking technology was usually used as drug screening, basing on Lock-and-key model of protein in order to better understand mechanisms. So the organic compounds of biochar from GC-MS analysis that acted as ligands were connected to HisG protein controlling L-histidine biosysthesis in . The result showed that the three organic molecules interacted with HisG protein by hydrogen bond. So we considered that these three compounds play regulatory roles in L-histidine biosysthesis, and the G expression fully supports this conclusion.
生物炭中的有机化合物发挥着激素类似物的作用,通过控制相关基因和蛋白质来刺激代谢物的表达。在本实验中,我们报道了与传统基因工程方法不同,生物炭处理促进了L-组氨酸的生物合成。相关结果表明,最适宜浓度为3%,7%为致死剂量。在高浓度处理中受到抑制。另一方面,对接技术通常用于药物筛选,基于蛋白质的锁钥模型,以便更好地理解其机制。因此,气相色谱-质谱分析中作为配体的生物炭有机化合物与控制L-组氨酸生物合成的HisG蛋白相连。结果表明,这三种有机分子通过氢键与HisG蛋白相互作用。因此,我们认为这三种化合物在L-组氨酸生物合成中起调节作用,而G表达充分支持这一结论。
