Sub-3 Å resolution structure of 110 kDa nitrite reductase determined by 200 kV cryogenic electron microscopy

Naruhiko Adachi, Takahide Yamaguchi, Toshio Moriya…·Toshiya Senda

The paper determines the sub-3 Å resolution cryo-EM structures of Achromobacter cycloclastes NiR at two pH values, identifies structural artifacts, and suggests local changes around the Cu site.
