  • Daniel Maresch,
  • Katarína Chovanová,
  • Jana Harichová and
  • Paul G. Furtmüller

Hybrid B heme peroxidases are recently discovered unique oxidoreductases present solely in the fungal kingdom. We have investigated two typical representatives from Magnaporthe oryzae—one of the most dangerous phytopathogens known as a causal a...

Ascorbate Peroxidase Neofunctionalization at the Origin of APX-R and APX-L: Evidence from Basal Archaeplastida

  • Fernanda Lazzarotto,
  • Paloma Koprovski Menguer,
  • Luiz-Eduardo Del-Bem,
  • Marcel Zámocký and
  • Márcia Margis-Pinheiro

Ascorbate peroxidases (APX) are class I members of the Peroxidase-Catalase superfamily, a large group of evolutionarily related but rather divergent enzymes. Through mining in public databases, unusual subsets of APX homologs were identified, disclos...
