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 ...

Investigation of the catalytic and structural roles of conserved histidines of human coproporphyrinogen oxidase using site-directed mutagenesis [PDF]
, 2007 Background: The catalytic contribution of four conserved histidines of human coproporphyrinogen oxidase (CPO) has been investigated using site-directed mutagenesis to change histidine (H) into alanine (A).

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 ...

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control
Pest Management Science, EarlyView.This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

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.

Identification of the Mitochondrial Heme Metabolism Complex. [PDF]
PLoS ONE, 2015 Heme is an essential cofactor for most organisms and all metazoans. While the individual enzymes involved in synthesis and utilization of heme are fairly well known, less is known about the intracellular trafficking of porphyrins and heme, or regulation ...

Kinetic evaluation of human cloned coproporphyrinogen oxidase using a ring isomer of the natural substrate [PDF]
, 2005 Background: The enzyme coproporphyrinogen oxidase (copro\u27gen oxidase) converts coproporphyrinogen-Ill (GIII) to protoporphyrinogen-IX via an intermediary monovinyl porphyrinogen. The A ring isomer coproporphyrinogen-IV (C-IV) has previously been shown

Chemical control strategies for Poa annua in managed turfgrass systems
Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.Abstract Poa annua L. is a widespread and persistent weed in managed turfgrass systems, exhibiting both annual and short‐lived perennial growth habits. Effective management requires an integrated approach, with chemical herbicides remaining a primary tool.
