Mitochondrial Targeting of Normal and Mutant Protoporphyrinogen Oxidase [PDF]
Journal of Biological Chemistry, 2003 We have investigated the signal sequence for mitochondrial transport of mutants (I12T, 78insC, IVS2-2a-->c, 338G-->C, R152C, 470A-->C, and L401F) and the wild type protoporphyrinogen oxidase (PPOX), which is the penultimate enzyme in the heme biosynthesis.

Expression of a cloned protoporphyrinogen oxidase.
Journal of Biological Chemistry, 1994 The previously cloned hem Y gene of Bacillus subtilis (Hansson, M., and Hederstedt, L. (1992) J. Bacteriol. 174, 8081-8093) has been expressed in Escherichia coli. The expressed protein has been shown to be the penultimate enzyme of the heme biosynthetic pathway, protoporphyrinogen oxidase (EC 1.3.3.4) and, thus, the gene designation should be hem G ...

Liver Transplantation and Other Hepatically Directed Therapies Do Not Change the Biochemical Phenotype nor Halt Progression of Leukodystrophy due to Biallelic <i>HMBS</i> Variants: A Case Report. [PDF]
JIMD RepABSTRACT Leukodystrophy due to biallelic HMBS variants is a rare condition distinct from acute intermittent porphyria (AIP). It is characterised by progressive leukoencephalopathy rather than acute attacks of neurovisceral symptoms. We report the ongoing clinical progression of a patient with leukodystrophy due to homozygous variants in HMBS [c.251C>A,

Activity of Antioxidant Enzymes in Euphorbia heterophylla Biotypes and their Relation to Cross Resistance to ALS and Protox Inhibitors [PDF]
Planta Daninha, 2018 : The characteristics of multiple resistance in Euphorbia heterophylla biotypes to herbicides that are inhibitors of ALS (Acetolactate synthase) and PPO (Protoporphyrinogen oxidase) and their responsible mechanisms are still not completely elucidated ...

The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

A New V361A Mutation in Amaranthus palmeri PPX2 Associated with PPO-Inhibiting Herbicide Resistance
Plants, 2023 Weeds resistant to PPO-inhibiting herbicides threaten the profitability of crop producers relying on this chemistry. In Amaranthus palmeri, mutations at G210 (∆G210) and R128 (R128G/M) of the PPX2 gene were reported to confer PPO-inhibitor resistance ...
