Insight into the selectivity and gating functions of Streptomyces lividans KcsA.

Proceedings of the National Academy of Sciences of the United States of America - 13 Mar 2007

Abstract excerpt

Streptomyces lividans KcsA is a 160-aa polypeptide that oligomerizes to form a tetrameric potassium channel. The three-dimensional structure of the polypeptides has been established, but the selectivity and gating functions of the channel remain unclear. It has been shown that the polypeptides copurify with two homopolymers, poly[(R)-3-hydroxybutyrate] (PHB) and inorganic polyphosphate (polyP), which have...
