In 2019,ACS Synthetic Biology included an article by Luo, Yuchang; Zhao, Qinqin; Liu, Qian; Feng, Yan. HPLC of Formula: 534-03-2. The article was titled 《An artificial biosynthetic pathway for 2-amino-1,3-propanediol production using metabolically engineered Escherichia coli》. The information in the text is summarized as follows:
2-Amino-1,3-propanediol (2-APD) is a chem. building block for the production of various value-added pharmaceuticals. However, the current manufacture of 2-APD predominantly relies on chem. processes by utilizing fossil fuel-derived and highly explosive raw materials. Herein, we established an artificial biosynthetic pathway for converting glucose to 2-APD in a metabolically engineered Escherichia coli. This artificial pathway employs an engineered heterogeneous aminotransferase RtxA for diverting dihydroxyacetone phosphate to generate 2-APD phosphate and an endogenous phosphatase for converting it into the target product 2-APD. Through fine-tuning the activity and solubility of RtxA for efficiently extending the glycolysis pathway, enhancing the metabolic recycling of amino-containing substrate supply via nitrogen-borrowing, and unlocking the dephosphorylation involved in the downstream pathway, the best metabolically engineered E. coli strain LYC-5 was constructed stepwise. Under aerobic conditions, a fed-batch fermentation of the strain LYC-5 produced 14.6 g/L 2-APD with a productivity of 0.122 g/L/h in a 6-L bioreactor, which was the highest reported titer to the best of our knowledge. This work demonstrates the great potential to provide an environmentally friendly and efficient approach for 2-APD production The experimental part of the paper was very detailed, including the reaction process of 2-Aminopropane-1,3-diol(cas: 534-03-2HPLC of Formula: 534-03-2)
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.HPLC of Formula: 534-03-2
