Journal ArticleDOI

Purple acid phosphatase from bovine spleen. Interactions at the active site in relation to the reaction mechanism.

Markus Dietrich, +3 more
- 01 Jul 1991 - 
TL;DR: A binuclear iron center is proposed for the purple acid phosphatase, which is bridged by a carboxylato and two aquo/hydroxo groups, but without a mu-oxo bridge.
Journal ArticleDOI

The amino acid sequence of the red kidney bean Fe(III)-Zn(II) purple acid phosphatase. Determination of the amino acid sequence by a combination of matrix-assisted laser desorption/ionization mass spectrometry and automated Edman sequencing.

Thomas Klabunde, +7 more
- 01 Dec 1994 - 
TL;DR: The employed strategy shows that the classical method, in combination with modern mass spectrometry, is an attractive approach for primary structure determination in addition to the DNA sequencing method.
Journal ArticleDOI

The oligosaccharides of the Fe(III)-Zn(II) purple acid phosphatase of the red kidney bean. Determination of the structure by a combination of matrix-assisted laser desorption/ionization mass spectrometry and selective enzymic degradation.

Bernd Stahl, +6 more
- 01 Mar 1994 - 
TL;DR: To reveal the sequence of the carbohydrate moiety including the linkage positions between the different saccharides, one of the glycopeptides was degraded by specific exoglycosidases and the detailed structure of this one glycan in conjunction with the respective mass spectra and the composition analysis were used to infer the structure of the other four glycans.
Journal ArticleDOI

Zn‐exchange and Mössbauer studies on the [Fe‐Fe] derivatives of the purple acid Fe(III)‐Zn(II)‐phosphatase from kidney beans

Hildegard Suerbaum, +5 more
- 01 May 1993 - 
TL;DR: Limited reduction of the oxidized enzyme with ascorbate delivers a mixture of the Fe(II)-Fe(II)/Fe(III)- Fe(III) species, but not the mixed valent Fe (III)-Fe (II) species; this indicates a half-integer spin system with antiferromagnetic coupling.
Journal ArticleDOI

Spectroscopic and exafs studies on catechol oxidases with dinuclear copper centers of type 3: Evidence for μ-η2:η2-peroxo-intermediates during the reaction with catechol

Annette Rompel, +8 more
