Ever since their discovery, bacterial tubulins, found in several Prosthecobacter species, have raised curiosity as they are closely related to eukaryotic tubulin. Deng and colleagues now present new evidence for the functional homology of the two cytoskeletal systems where in vitro reconstituted Btub-microtubules display eukaryote-like biochemical and dynamic properties.

细菌微管蛋白：真核细胞微管细胞骨架。

自从发现以来，在几种Prosthecobacter物种中发现的细菌微管蛋白就引起了人们的好奇心，因为它们与真核微管蛋白密切相关。Deng及其同事现在为这两个细胞骨架系统的功能同源性提供了新的证据，其中体外重建的Btub微管显示出类似真核生物的生物化学和动态特性。
