The sbiT-sbiR-sbiS operon of Stenotrophomonas maltophilia encodes an inner-membrane protein SbiT and a SbiS-SbiR two-component regulatory system. A sbiT mutant displayed a growth defect in LB agar. Mechanism studies revealed that sbiT deletion resulted in SbiSR activation and gloIo upregulation, which increased intracellular ROS level and caused growth defect.
嗜麦芽寡养单胞菌的 sbiT-sbiR-sbiS 操纵子编码一个内膜蛋白 SbiT 和一个 SbiS-SbiR 双组分调控系统。sbiT 突变体在 LB 琼脂上表现出生长缺陷。机制研究表明,sbiT 缺失导致 SbiSR 激活和 gloIo 上调,增加了细胞内 ROS 水平并导致生长缺陷。
