Conformational Stability and Crystal Packing: Polymorphism in Neurospora Crassa Cat-3 Acta Crystallogr.,Sect.F, 69:753-, 2013 Cited by PubMed Abstract: Polymorphism is frequently observed from different crystallization conditions. In proteins, the effect on conformational variability is poorly documented, with only a few reported examples. Here, three polymorphic crystal structures determined for a large-subunit catalase, CAT-3 from Neurospora crassa, are reported. Two of them belonged to new space groups, P1 and P43212, and a third structure belonged to the same space group, P212121, as the previously deposited 2.3 Å resolution structure (PDB entry 3ej6), but had a higher resolution (1.95 Å). Comparisons between these polymorphic structures highlight the conformational stability of tetrameric CAT-3 and reveal a distortion in the tetrameric structure that has not previously been described.
