TL;DR: The crystal structure of the anaerobic complex of Pseudomonas putida protocatechuate 3, 4-dioxygenase bound with the alternative substrate, 3,4-dihydroxyphenylacetate (HPCA), and the model for the crystal structure in which the C3 phenolic function occupies the Fe3+ ligand site opposite the endogenous ligand Tyr408(Oeta) (108beta).

TL;DR: The solution structures of the binuclear Mn centers in arginase, Mn catalase, and the Mn-substituted forms of the Fe enzymes ribonucleotide reductase and hemerythrin have been determined using X-ray absorption spectroscopy, suggesting either that there are no single atom bridges in these cases or that the Mn...Mn interactions are more disordered.

TL;DR: Electronic and vibrational spectroscopic changes associated with changes in spin state, oxidation state, and ligation of the heme in HRP:sol-gel were shown to correlate with those of HRP in solution, showing that the he me remains a viable ligand-binding complex.

TL;DR: A series of (r-oxo)diiron(III) complexes of tris(2-pyridylmethyl)amine (TPA), [Fe 2 O(TPA) 2 (L)] (ClO 4 ) 2, were synthesis and characterized where L represents the bridging tetraoxo anion ligands sulfate, phosphate, arsenate vanadate, and molybdate as discussed by the authors.
