Structural foundations of potassium selectivity in channelrhodopsins

E. G. Govorunova, O. A. Sineshchekov, L. Brown, A.-N. Bondar, J. L. Spudich

This study identifies structural motifs in kalium channelrhodopsins (KCRs) responsible for their K+ selectivity, showing that specific mutations convert Na+ selectivity to K+ selectivity.

Preproteins couple the intrinsic dynamics of SecA to its ATPase cycle to translocate via a catch and release mechanism

S. Krishnamurthy, M. F. Sardis, N. Eleftheriadis, K. E. Chatzi, J. H. Smit, K. Karathanou, G. Gouridis, A. G. Portaliou, A.-N. Bondar, S. Karamanou, A. Economou

The paper reveals how SecA's intrinsic dynamics and preprotein interactions enable translocation via a catch and release mechanism.

A nexus of intrinsic dynamics underlies translocase priming

S. Krisnamurthy, N. Eleftheriadis, K. Karathanou, J. H. Smit, A. Portaliou, K. E. Chatzi, S. Karamanou, A.-N. Bondar, G. Gouridis, A. Economou

This study identifies a dynamic nexus in SecA that primes the Sec translocase for preprotein binding through conserved structural motions and interactions.
