    Abstract Structural biology continues to benefit from an expanding toolkit, which is helping to gain unprecedented insight into the assembly and organization of multi-protein machineries, enzyme mechanisms and ligand/inhibitor binding. During the last ten years, cryoEM has become widely available and has provided a major boost to structure determination of membrane proteins and large multi-protein complexes. Many of the structures have now been made available at resolutions around 2 Å, where fundamental questions regarding enzyme mechanisms can be addressed. Over the years, the abbreviation cryoEM has been understood to stand for different things. We wish the wider community to engage and clarify the definition of cryoEM so that the expanding literature involving cryoEM is unified.

    Abstract Metalloproteins comprise at least a third of all proteins that utilize redox properties of transition metals on their own or as parts of cofactors. The development of third generation storage ring sources and X-ray free-electron lasers with femtosecond pulses in the first decade of the 21st century has transformed metalloprotein crystallography. In the past decade, cryogenic-electron microscopy single-particle analysis, which does not require crystallization of biological samples has been extensively utilized, particularly for membrane-bound metalloprotein systems. Here, we explore recent frontiers in metalloprotein crystallography and cryogenic electron microscopy, organized for convenience under three metalloprotein-centered biological cycles, focusing on contributions from each technique, their synergy and the ability to preserve metals' redox states when subjected to a particular probe.
