In a recent publication in PNAS the group of Sonja Albers from the University of Freiburg demonstrates that the archaeal CheY protein shares the overall structure and mechanism of magnesium-dependent phosphorylation with its bacterial counterpart. Furthermore they show that phosphorylation-dependent activation, and conserved residues in the archaeal CheY helix α4, are important for interaction with the archaeal-specific adaptor protein CheF. Our EM unit contributed electron micrographs of H. volcanii archaella. Thank you Sonja for the fruitful collaboration.
