Plant transglutaminases, enzymes involved in protein cross-linking, are increasingly identified. This review compares their characteristics and functions to animal transglutaminases, providing insights into plant biology.

Area of Science:

  • Biochemistry
  • Plant Biology
  • Enzymology

Background:

  • Transglutaminases are enzymes catalyzing protein cross-linking reactions.
  • Animal transglutaminases are well-characterized with diverse physiological roles.
  • Plant transglutaminases have been recently identified and are less understood.

Purpose of the Study:

  • To review the identification procedures and characteristics of plant transglutaminases.
  • To discuss the potential functions of plant transglutaminases.
  • To compare plant transglutaminases with their animal counterparts.

Main Methods:

  • Literature review of studies on plant, animal, and microbial transglutaminases.
  • Comparative analysis of enzyme characteristics (e.g., substrate specificity, reaction mechanism).

  • Discussion of potential physiological roles in plants based on existing data.

    • Main Results:

    • Plant transglutaminases share similarities with animal transglutaminases in their catalytic mechanism.
    • Evidence suggests diverse roles for plant transglutaminases, including cell wall formation and stress response.
    • Studies in lower organisms and Angiosperms provide a foundation for understanding these enzymes.

    Conclusions:

    • Plant transglutaminases represent a conserved enzymatic activity with significant functional implications in plants.
    • Further research is needed to fully elucidate the specific roles and regulation of plant transglutaminases.
    • Comparative enzymology provides a valuable framework for advancing plant transglutaminase research.
