摘 要:摘 要:假单胞菌是一类重要的环境微生物,具有卓越的物质分解转化和合成能力,利用莽草酸途径可以合成多种芳香族化合物,包括羟基苯甲酸等平台产品。羟基苯甲酸,如2- 羟基苯甲酸(2-HBA)、3- 羟基苯甲酸(3-HBA)、4- 羟基苯甲酸(4-HBA) 和3,4- 二羟基苯甲酸(PCA),在假单胞菌碳代谢中起着重要作用。以羟基苯甲酸作为合成生物学的一个基本模块,用于合成高附加值的衍生物具有广阔的前景。探究基于不同羟基苯甲酸为前体的细胞工厂建立,可为假单胞菌合成生物学平台的应用和构建打下良好的基础。

Abstract: Abstract: Pseudomonas has been well engineered as typical microorganisms for value-added aromatic compound production including hydroxybenzoate acid on the basis of shikimate pathway. Hydroxybenzoate acids, such as 2-hydroxybenzoate acid (2-HBA), 3-hydroxybenzoate acid (3-HBA), 4-hydroxybenzoate acid (4-HBA) and 3,4-dihydroxybenzoate acid (PCA), play key roles in the microbial carbon metabolism of Pseudomonas. Using the versatile intermediate platform of hydroxybenzoate acid, a lot of high-value products can be synthesized efficiently. With a close-up at the future perspectives, a series of commercial biological products could be developed through the design and construction of artificial biosynthetic pathways in conventional microorganisms Pseudomonas for synthetic biology platform construction.
