Analysis of The Transmembrane Structure of The Receptor Protein AgrC in agr System of Staphylococcus aureus
金黄色葡萄球菌agr系统受体蛋白AgrC的跨膜结构分析析

Activation of the agr system in Staphylococcus aureus is initiated by the binding of a specific autoinducing peptide (AIPs) to the extracellular domain of AgrC. Comparison of the AgrC-IV and AgrC-I sequences revealed a set of divergent residues in the region of the receptor's second extracellular loop that could be responsible. AgrC-II could be interacting in the region of the receptor's first or second extracellular loop with AIP II.
