The interaction of Fe(II) and Fe(III) with the 'high-affinity Mn-binding site' in Mn-depleted photosystem II (PSII) was investigated using diphenilcarbazide (DPC)/2,6-dichlorophenol-indophenol (DCIP) inhibition assay. Fe(III) was ineffective in the inhibition of DPC-DCIP reaction while Fe(II) decreased the rate of DCIP

In this paper, the reaction mechanism of the system of thallium (III)-copper(II)-ethylenediaminete-traacetate-hydrogen peroxide-diphenylcarbazide has been studied by spectrophotometric method. The experimental results show that the reaction mechanism of the system is based on the replacement of copper(II) by thallium (III)

Oxidation of Cr(III) during sonication in carbonated aqueous solutions saturated with CCl4 leads to the quantitative formation of Cr(VI) and provides a simple and rapid method for spectrophotometric chromium determination with 1,5-diphenylcarbazide. The key to this method is the production

The inhibition of DPC-mediated DCIP photoreduction by exogenous MnCl2 in Tris-treated photosystem II (PSII) membrane fragments has been used to probe for amino acids on the PSII reaction center proteins, including D1His337, that provide ligands for binding manganese [Preston, C.
