Hi! I am running a small experiment dealing with structural heterogeneity of the ribosome, actually of ribosomes across all domains of life. It's entirely computational: I get cryoEM samples(below) from PDB, parse the crystallographic profiles and see if I can enclose on physical clusters of proteins that persist across domains of life (i.e. uL4 reliably neighbors uL22 according to this ontology) and things like that. So far I've been working with the following dataset of eukaryotic/eubacterial/archeal macromolecules and am feeling pretty shackled by it at this point.
I would be very happy to augment this dataset with any number of "similar" ribosomes to put through the algorithm, but I don't know much about exemplar species to draw from and decided to ask here if somebody would recommend some more or less well-studied species(or straight-up PDB IDs) that would make a good addition. If you could point a boy to where I can "just get more" that'd be even more awesome. I'm not a biologist by training so you probably know of some obvious resource I don't.
I have no other constraints on what the targets are. Thank you so much and stay safe!
