Size matters: optimal mask diameter and box size for single-particle cryogenic electron microscopy

Toshio Moriya, Naruhiko Adachi, Masato Kawasaki, Yusuke Yamada, Akira Shinoda, Kotaro Koiwai, Fumiaki Yumoto, Toshiya Senda

This paper optimizes mask diameter and box size for 200 keV cryo-EM to improve resolution for proteins under 200 kDa.

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

Naruhiko Adachi, Takahide Yamaguchi, Toshio Moriya, Masato Kawasaki, Kotaro Koiwai, Akira Shinoda, Yusuke Yamada, Fumiaki Yumoto, Takamitsu Kohzuma, 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.
