Abstract

Two hundred genes or 3% of the known or putative protein-coding genes of the filamentous freshwater cyanobacterium Anabaena sp. PCC 7120 encode domains of ATP-binding cassette (ABC) transporters. Detailed characterization of some of these transporters (14-15 importers and 5 exporters) has revealed their crucial roles in the complex lifestyle of this multicellular photoautotroph, which is able to differentiate specialized cells for nitrogen fixation. This review summarizes the characteristics of the ABC transporters of Anabaena sp. PCC 7120 known to date.

摘要

丝状淡水蓝藻鱼腥藻Anabaena sp. PCC 7120中，200个基因（占已知或推测的蛋白质编码基因的3%）编码ATP结合盒（ABC）转运蛋白结构域。对其中一些转运蛋白（14 - 15个输入蛋白和5个输出蛋白）的详细表征揭示了它们在这种多细胞光合自养生物复杂生活方式中的关键作用，该生物能够分化出用于固氮的特化细胞。本综述总结了迄今为止已知的鱼腥藻Anabaena sp. PCC 7120的ABC转运蛋白的特征。
