Simultaneous liquid-chromatographic determination of zinc protoporphyrin IX, protoporphyrin IX, and coproporphyrin in whole blood.
We describe a method for simultaneously measuring concentrations of coproporphyrin, zinc protoporphyrin IX, and protoporphyrin IX in whole blood by liquid chromatography, with use of reversed-phase ion-pair system, fluorometric detection, and internal standardization. Each analysis requires 10 microL of whole blood and 15 min total analysis time. Analytical recovery ranged from 84 to 92%, day-t...
متن کاملAccumulation of Protoporphyrin IX in the Presence of Peroxidizing Herbicides
Peroxidizing herbicides were assayed for their capacity to accumulate tetrapyrrole-like compounds in the liquid culture medium when growing the xanthophycean alga Bumilleriopsis filiformis. W e have isolated and purified this compound by H P L C . For identification optical, fluorescence, N M R and mass spectroscopy were employed. All these techniques showed that the accumulation product is pro...
متن کاملThe Enzymic Conversion of Protoporphyrinogen IX to Protoporphyrin IX
The oxidation of protoporphyrinogen IX to protoporphyrin TX in yeast cells is enzyme-dependent. The enzyme, protoporphyrinogen oxidase, associated with purified mitochondria isolated from Saccharomyces cereuisiae was solubilized by sonic treatment in the presence of detergent and partially purified. The molecular weight of the enzyme was 180,000 f 18,000. The purified preparation could be store...
متن کاملChloroplast Biogenesis 65 : Enzymic Conversion of Protoporphyrin IX to Mg-Protoporphyrin IX in a Subplastidic Membrane Fraction of Cucumber Etiochloroplasts.
The preparation from Percoll-purified cucumber (Cucumis sativus)etiochloroplasts of a subplastidic membrane fraction that is capable of high rates of Mg insertion into protoporphyrin IX is described. The plastid stroma was inactive when used either alone or in combination with the membrane fraction. Successful preparation of the subplastidic membrane fraction required that Mg-protoporphyrin che...
متن کاملSeparation of Mg-Protoporphyrin IX and Mg-Protoporphyrin IX Monomethyl Ester Synthesized de novo by Developing Cucumber Etioplasts.
High pressure liquid chromatography was used to demonstrate that chelation of Mg(2+) into protoporphyrin IX precedes methylation in isolated greening etioplasts from cucumber (Cucumis sativus L. var. Beit Alpha) cotyledons. Mg-protoporphyrin IX synthesized in vitro from protoporphyrin IX, Mg(2+), and ATP or exogenous Mg-protoporphyrin IX could serve as substrates for the methylation step. In ei...
