鞘氨醇单胞菌A1是一种新发现的能形成凹坑的细菌，它通过一个凹坑依赖的转运系统将一种大分子（藻酸盐）直接整合到其细胞质中，我们称之为超通道。一个坑是一个新的，高维的器官获得通过流动性和重组的细胞表面分子，包括鞭毛蛋白，并通过合作与运输机制在细胞中，这赋予细菌细胞一个更有效的方式来确保和同化大分子。对超通道的分析改变了关于细胞表面的流动性和功能，细胞表面器官的进化和起源，包括鞭毛，运输和大分子同化系统，以及新陈代谢的发散和能量学的一般想法。
Sphingomonas species A1 is a newly identified pit-forming bacterium that directly incorporates a macromolecule (alginate) into its cytoplasm through a pit-dependent transport system, which we termed a superchannel. A pit is a novel, high-dimensional organ acquired through the fluidity and reconstitution of cell surface molecules, including flagellin, and through cooperation with the transport machinery in the cells, which confers upon bacterial cells a more efficient way to secure and assimilate macromolecules. The analysis of the superchannel changes general ideas regarding the fluidity and function of the cell surface, evolution and origin of cell-surface organs, including flagella, transport, and assimilation systems of macromolecules, and the divergence and energetics of metabolism.
