An unprecedented Fe(III)(mu-OH)Zn(II) complex that mimics the structural and functional properties of purple acid phosphatases.

TL;DR: It is demonstrated that the μ-hydroxo group in the {FeIII(μ-OH)(μ-ROPO3)ZnII} intermediate is unable to hydrolyze the monoester 2,4-dinitrophenylphosphate (DNPP), which suggests that theμ-hydroxyo group is a significantly poorer nucleophile than the terminally FeIII-bound OH- group.
Journal ArticleDOI
New FeIIIZnII Complex Containing a Single Terminal Fe−Ophenolate Bond as a Structural and Functional Model for the Active Site of Red Kidney Bean Purple Acid Phosphatase
TL;DR: Solution studies of 1 indicate that a pH-induced change of the bridging acetate occurs, and the formation of an active [(OH)Fe(III)Zn(II)(OH(2))] species as a highly efficient catalyst under weakly acidic conditions for phosphate diesters hydrolysis is proposed.
Journal ArticleDOI
Synthesis, Structure, Properties, and Phosphatase-Like Activity of the First Heterodinuclear FeIIIMnII Complex with the Unsymmetric Ligand H2BPBPMP as a Model for the PAP in Sweet Potato
TL;DR: The new heterodinuclear mixed valence complex [Fe(III)Mn(II)(BPBPMP)(OAc)(2)]ClO(4) (1) with the unsymmetrical N(5)O(2) donor ligand 2-bis[((2-pyridylmethyl)-aminomethyl)-6-(2-hydroxybenzyl)(2- pyrIDylmethyl))-aminometHyl]-4
Journal ArticleDOI
Influence of ligand rigidity and ring substitution on the structural and electronic behavior of trivalent iron and gallium complexes with asymmetric tridentate ligands.
Camille Imbert,Hrant P. Hratchian,Mauricio Lanznaster,Mary Jane Heeg,Lew M. Hryhorczuk,Bruce R. McGarvey,H. Bernhard Schlegel,Cláudio N. Verani +7 more
TL;DR: Monometallic species with d5 high-spin iron and d10 gallium were synthesized and characterized to assess the influence of the ligand rigidity and the presence of tertiary butyl-substituted phenol rings on their steric, electronic, and redox behavior.
Journal ArticleDOI
A new heterobinuclear FeIIICuII complex with a single terminal FeIII–O(phenolate) bond. Relevance to purple acid phosphatases and nucleases
Mauricio Lanznaster,Ademir Neves,Adailton J. Bortoluzzi,Veronika V. E. Aires,Bruno Szpoganicz,Hernán Terenzi,Patricia Cardoso Severino,Julie M. Fuller,Simon C. Drew,Lawrence R. Gahan,Graeme R. Hanson,Mark J. Riley,Gerhard Schenk +12 more
TL;DR: 1 is one of the most effective model complexes to date, mimicking the function of nucleases, and is significantly more reactive than its isostructural homologues with different metal composition.
