Anabaena sp. PCC 7120 is a filamentous cyanobacterium that serves as a model to analyze prokaryotic cell differentiation, evolutionary development of plastids, and the regulation of nitrogen fixation. The cell wall is the cellular structure in contact with the surrounding medium. To understand the dynamics of the cell wall proteome during cell differentiation, the cell wall from Anabaena heterocysts was enriched and analyzed. In line with the recently proposed continuity of the outer membrane along the Anabaena filament, most of the proteins identified in the heterocyst cell-wall fraction are also present in the cell wall of vegetative cells, even though the lipid content of both membranes is different.
鱼腥藻PCC 7120是一种丝状蓝细菌，可作为分析原核细胞分化、质体进化发育以及固氮调控的模型。细胞壁是与周围介质接触的细胞结构。为了了解细胞分化过程中细胞壁蛋白质组的动态变化，对鱼腥藻异形胞的细胞壁进行了富集和分析。与最近提出的沿鱼腥藻丝状体的外膜连续性一致，在异形胞细胞壁组分中鉴定出的大多数蛋白质也存在于营养细胞的细胞壁中，尽管两种膜的脂质含量不同。
