Critical evaluation of three cryo-EM structures of particulate methane monooxygenase by quantum refinement. [PDF]

Acta Crystallogr D Struct Biol
We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites
