The novel two-component systems NsrRS and LcrRS are individually associated with resistance against the distinct lantibiotics nisin A and nukacin ISK-1 in Streptococcus mutans. NsrRS regulates the expression of NsrX, which is associated with nisin A binding, and LcrRS regulates the expression of the ABC transporter LctFEG.
新型双组份系统 NsrRS 和 LcrRS 分别与变链菌中不同的羊毛硫抗生素乳链菌肽 A 和 nukacin ISK-1 的抗性有关。NsrRS 调节与乳链菌肽 A 结合有关的 NsrX 的表达,而 LcrRS 调节 ABC 转运体 LctFEG 的表达。
