Quorumpeps® is a resource of quorum sensing signalling peptides. This database is managed by Ghent University. Based upon your input, this search page will give you all information (structure, activity, physicochemical properties and related literature). The database is linked to a manuscript entitled "Quorumpeps database: chemical space, microbial origin and functionality of quorum sensing peptides", in which the origin of the different peptides and their quorum sensing pathways and methods are described.
