"What do protein crystallographers dream of?" is the question asked by Ananyo Bhattacharya in an article published in Nature [Protein structures: Structures of desire]. The structures of many protein complexes have been determined but crystallographers have a list of holy grails that, so far, have eluded them. It's an interesting list and one that I mostly agree with. Can you identify the structure shown here in cartoon form?
One glaring omission is pyruvate dehydrogenase. Lot's of people want to see that structure. Other notable omissions include complex I of the membrane-associated electron transport chain and the protein import complex of the endoplasmic reticulum. Don't protein crystallographers dream of those?
