Abstract

KpsT utilizes ATP to effect translocation of the polysialic acid capsule of Escherichia coli K1. We have previously proposed a mechanistic model for the action of this protein. Here, we provide evidence to support two predictions of the model: that KpsT associates with polymer and that KpsT is accessible from the periplasmic surface of the inner membrane.
