Phylogenetic Relationships in Class I of the Superfamily of Bacterial, Fungal, and Plant Peroxidases

Author: Marcel Zámocký

Field: Molecular Biology

Document Content: This study investigates the molecular phylogeny of catalase-peroxidases, cytochrome c peroxidases, and ascorbate peroxidases. By analyzing sixty representative sequences from bacterial, fungal, and plant heme peroxidases, the research aims to understand the evolutionary history and relationships within Class I of the heme peroxidase superfamily. The analysis reveals four distinct clades, suggesting early evolutionary segregation of these groups. The findings indicate that gene duplication events, particularly in the evolution of catalase-peroxidases, occurred later in the superfamily’s development. The study also presents evidence for the widespread distribution of Class I heme peroxidases across prokaryotes and eukaryotes, driven by a birth-and-death evolutionary process.
