Abstract
Intracellular localization of triterpenic membrane stabilizers of the hopane series is described for the first time for a cyanobacterium. In Synechocystis PCC 6714, a bacteriohopanetetrol derivative (main compound) and diplopterol were detected in cell wall (CW) and thylakoid membrane (TM). Both hopanoids were enriched 4.5-fold and 9.0-fold in CW and outer membrane (OM) fractions, respectively, compared to TMs.
摘要
首次描述了蓝细菌中藿烷系列三萜类膜稳定剂的细胞内定位。在聚球藻PCC 6714中，在细胞壁（CW）和类囊体膜（TM）中检测到一种细菌藿四醇衍生物（主要化合物）和双扇醇。与类囊体膜相比，这两种藿烷类化合物在细胞壁和外膜（OM）组分中的富集倍数分别为4.5倍和9.0倍。
