It is my impression that when the "author determined" biological assembly (REMARK 350) specifies the same structure as the asymmetric unit, sometimes the authors simply forgot to specify a known assembly during PDB deposition. Does anyone know of PDB entries where this has occurred?

Hi Eric Here are a few cases for which the REMARK 350 annotated by authors says the protein is a monomer but the authors in the paper say that the proteins are actually dimers and prove it with independent experimental methods (like AUC, gel filtration or light scattering): 3pc4 1wxi 1w3u 2ex2 2fwv 1mdo 1ytq 1v2x Thus my guess is that these cases are most likely authors annotating a monomer by default, since the asymmetric unit is monomeric.
