Multiple lines of evidence demonstrate that a single N-glycan on one receptor influences the strength of a cytotoxic response elicited by natural killer cells following stimulation with an antibody-coated target.
LptC regulates the LPS entry gate in LptB2FG, likely through a dynamic behavior of its transmembrane helix, while the β-jellyroll domains are tethered in the periplasm.
The first structural and biochemical study of the role of the ATP-cone in anaerobic ribonucleotide reductases shows that dATP allosterically prevents transfer of a glycyl radical to the substrate.
