Area of Science:

  • Biochemistry
  • Biotechnology
  • Enzymology

Background:

  • Cutinases are enzymes that degrade cutin, a major component of plant cuticles.
  • Understanding cutinase function is crucial for developing novel biocatalysts.
  • Fungal cutinases, particularly from Fusarium solani f. pisi, offer significant biotechnological potential.

Purpose of the Study:

  • To review the natural roles and biotechnological applications of cutinases.
  • To analyze the structure-function relationship of a fungal cutinase.
  • To discuss the optimization of cutinase-based biocatalytic processes.

Main Methods:

  • Cloning and expression of fungal cutinase in microbial hosts (E. coli, S. cerevisiae).
  • Three-dimensional structural analysis of cutinase.
