Abstract
In this review, we discuss the kps cluster of Escherichia coli as the paradigm for the ABC capsular polysaccharide exporter (CPSE) family. Components of the cluster form a multimeric protein complex consisting of both biosynthetic and export machinery. We compare the Kps exporter with capsule export systems from other members of the CPSE family.
