摘要: 螺旋霉素(spiramycin,SPM)是十六元环大环内酯类抗生素,在临床上占有重要的地位,其产生菌为生二素链霉菌(S. ambofaciens)。螺旋霉素由福洛氨糖(forosamine)、碳霉氨糖(mycaminose)和碳霉糖(mycarose)3个部分组成。简要介绍了螺旋霉素的理化性质和药理作用,以及生物合成途径与发酵工艺等方面的研究状况,根据螺旋霉素生物合成途径,分别从分子水平、基因水平及发酵工艺等3个方面对通过添加前体或对前体有利的物质及定向过量表达某些重要基因等提高螺旋霉素产量的技术进行了简要概述。

Abstract: Spiramycin is a 16-membered ring macrolide antibiotics,and plays an important role in clinical practice. It is produced by S. ambofaciens. Spiramycin is composed of three parts:forosamine,mycaminose and mycarose. This article describes briefly the physicochemical properties and pharmacological effects of the spiramycin,and recent advances on the biosynthetic pathway and the fermentation process. According to biosynthetic pathway of spiramycin,the techniques for increasing its yield,i.e.,adding precursor or beneficial substances to precursor,and direct overexpression of some important genes,were briefly summarized from 3 aspects of the molecular and genetic level,as well as fermentation process,respectively

Key words: spiramycin, biosynthesis, gene-regulation, precursor
