Publikováno v: Bulletin of the Chemical Society of Japan. 90:169-177

The unusual magnetic/spectroscopic properties of Cytochrome c′ (Cyt c′) have been discussed, especially concerning the possibility of a quantum mechanically mixed-spin configuration of heme Fe(III). Here, four unique-spin species were identified

X-ray crystallographic evidence for the simultaneous presence of axial and rhombic sites in cupredoxins: atomic resolution X-ray crystal structure analysis of pseudoazurin and DFT modelling

Autor: K. Akao, S. Asamura, Robert K. Szilagyi, Akiko Takashina, Masaki Unno, Takamitsu Kohzuma, Takahide Yamaguchi

Publikováno v: RSC Advances. 6:88358-88365

Crystal structure refinement of pseudoazurin from Achromobacter cycloclastes (AcPAz) was carried out at atomic (1.10 A) resolution. The copper ion was localized in two positions at the metal binding site of AcPAz. The occupancies of the copper sites

X-ray Crystallographic Elucidation for the Alkaline High-spin State Transition of Iron(III) Cytochrome c′ from Alcaligenes xylosoxidans NCIMB 11015

Autor: Takamitsu Kohzuma, Masaki Unno, Akiko Takashina

Publikováno v: Chemistry Letters. 44:268-270

The first X-ray crystallographic study for the alkaline structure transition of cytochrome c′ was performed. Precise X-ray crystal structures of acidic (pH 6.0) and alkaline (pH 10.4) iron(III) cyt...

The type 1 copper site of pseudoazurin: axial and rhombic

Autor: Silvia Sottini, Peter Gast, Edgar J. J. Groenen, Akiko Takashina, Takamitsu Kohzuma, Risa Aoki, Takahide Yamaguchi, Freek G.J. Broeren

Publikováno v: Journal of inorganic biochemistry. 137

We report on a high-frequency electron-paramagnetic-resonance study of the type 1 copper site of pseudoazurin. The spectra fully resolve the contribution of a nearly axial spectrum besides the rhombic spectrum, which unequivocally proves the existenc
