摘要

大肠杆菌TrkG和TrkH转运体含有一个独特的n端Domain-0 （D0）。我们的研究结果表明，D0支持TrkG的功能和稳定性，使K+和Na+摄取，而不是trkh介导的K+摄取所必需的。这种差异可归因于D0在TrkG核心跨膜结构域中稳定极性残基的作用。

Functional characterization of an additional transmembrane domain unique to TrkG and TrkH in Escherichia coli.

Escherichia coli TrkG and TrkH transporters contain a unique N-terminal Domain-0 (D0). Our findings reveal that D0 supports both the function and stability of TrkG, enabling K+ and Na+ uptake, whereas it is not essential for TrkH-mediated K+ uptake. This difference can be attributed to D0 role in stabilizing polar residues within TrkG core transmembrane domains.
