The mitochondrial location of protoporphyrinogen oxidase [PDF]
Using the digitonin method and subsequent fractionation of rat liver mitochondria, protoporphyrinogen oxidase (penultimate enzyme in the heme biosynthesis pathway) was found to be closely associated with the mitochondrial inner membrane fraction.Chemical treatment with non‐specific probes (trypsin and diazobenzene sulfonate) of either intact or ...

Protoporphyrinogen Oxidase Inhibitor: An Ideal Target for Herbicide Discovery
As the last common enzyme in the biosynthetic pathway leading to heme and chlorophyll, protoporphyrinogen oxidase (PPO; EC 1.3.3.4) is an ideal target for herbicide development.

Safety assessment of membrane-associated protoporphyrinogen IX oxidase from Enterobacter cloacae expressed in genetically modified crops [PDF]
Crops tolerant to protoporphyrinogen IX oxidase (PPO)-inhibiting herbicides were developed by expressing an herbicide insensitive PPO, a membrane-associated protein from Enterobacter cloacae. E.

Design, Synthesis and Herbicidal Activity of 5-(1-Amino-4-phenoxybutylidene)barbituric Acid Derivatives Containing an Enamino Diketone Motif [PDF]
In continuation of our efforts to identify novel herbicide lead compounds, twenty new 5-(1-amino-4-phenoxybutylidene)barbituric acid derivatives containing an enamino diketone motif were synthesized and evaluated for their herbicidal activities.

Discovery of Novel Phenoxypyridine as Promising Protoporphyrinogen Ix Oxidase Inhibitors
Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is a significant target for the discovery of novel bleaching herbicides. Starting from the active fragments of several known commercial herbicides, a series of PPO inhibitors with diphenyl ether scaffolds were designed and synthesized by substructure splicing and bioisosterism methods.

Glufosinate enhances the activity of protoporphyrinogen oxidase inhibitors [PDF]
AbstractGlufosinate inhibits glutamine synthetase (GS), a key enzyme for amino acid metabolism and photorespiration. Protoporphyrinogen oxidase (PPO) inhibitors block chlorophyll biosynthesis and cause protoporphyrin accumulation, a highly photodynamic intermediate.

Proteomics analysis of nitrogen stress on the influence of carbon and nitrogen metabolism of flue-cured tobacco [PDF]
Nitrogen stress is the main abiotic stress factor affecting the carbon and nitrogen balance of flue-cured tobacco. Using tandem mass tag (TMT) proteomics, we identified 157 differentially expressed proteins (DEPs) under low nitrogen (LN, 60 kg/hm2; 65 ...

Resistance to Protoporphyrinogen Oxidase-inhibiting Compound S23142 from Overproduction of Mitochondrial Protoporphyrinogen Oxidase by Gene Amplification in Photomixotrophic Tobacco Cells [PDF]
Tobacco YZI-IS cells exhibit a 150-fold greater resistance to the protoporphyrinogen oxidase (Protox)-inhibiting compound, S23142, from wild-type tobacco cells. To investigate the mechanism for this S23142 resistance, the protein level, enzymatic activity, and sensitivity to S23142 in two Protox isoenzymes (plastidal and mitochondrial forms) were ...
