AMethodforStructure5
ConclusionsQuorum-sensing signaling systems involving the interaction between a signaling peptide and its cognate histidine kinase receptor are widely distributed in Gram-positive bacteria. Structure–activity analysis of signaling peptides and their analogs may provide clues for understanding the specificity of peptide–receptor interactions in these bacteria. In this report, we have used the S. mutans CSP a......阅读全文
