Protoporphyrin IX Content Correlates with Activity of Photobleaching Herbicides.
Several laboratories have demonstrated recently that photobleaching herbicides such as acifluorfen and oxadiazon cause accumulation of protoporphyrin IX (PPIX), a photodynamic pigment capable of herbicidal activity. We investigated, in acifluorfen-treated tissues, the in vivo stability of PPIX, the kinetics of accumulation, and the correlation between concentration of PPIX and herbicidal damage...
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 کاملFerrochelatase activity and protoporphyrin IX utilization in Haemophilus influenzae.
Previous research showed that the heme-requiring human pathogen Haemophilus influenzae lacks the first six of the seven enzymes required for heme synthesis, starting with the precursor, 5-amino levulinic acid. In this study, I demonstrated either directly or by reasonable inference that all 57 strains of H. influenzae examined, including 2 unable to grow on protoporphyrin IX, possess ferrochela...
متن کاملSimultaneous 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 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...
