摘　　要：吡咯喹啉醌(pyrroloquinoline quinone,PQQ)是一种多肽修饰类天然产物,是继烟酰胺和核黄素之后第三类辅酶,具有抗氧化、抗衰老、提高免疫力等重要生理功能,在医药、保健等领域具有重要价值。目前,PQQ的大规模制备仍然存在诸多问题,限制了PQQ的广泛应用。当前迫切需求低成本的合成方式,以充分实现其广阔的应用潜力。综述了近年来PQQ生物合成途径的解析、关键酶的催化反应机理以及高产菌株选育等方面的研究动态及发展趋势,并针对PQQ生物合成微生物细胞工厂构建研究策略提出了建议及展望。Pyrroloquinoline quinone(PQQ)is a ribosomally synthesized and post-translationally modified peptide that has been recognized as the third class of redox cofactors in addition to the well-known nicotinamides(NAD(P)+)and flavins(FAD,FMN).It is widely distributed in organisms and has physiological functions such as antioxidation.It has broad application prospects in the fields of medicine,food and cosmetics.However,the lack of an efficient microbial cell factory limits the industrial production efficiency of PQQ.In this paper,we reviewed the current research on the biosynthesis pathway of PQQ,the structures of key enzymes,as well as metabolic engineering strategies for the construction of high-yielding strains.These advances will provide a basis for finally achieving stable PQQ biosynthesis in microbial cell factories.
