Enzyme or Coenzyme

Protein-Arginine Deiminase Type 1

A peptidylarginine deiminase isoenzyme. It is a post-translational modification enzyme that catalyzes the conversion of protein-bound ARGININE residues to CITRULLINE residues in a CALCIUM ion-dependent manner. It functions within the epidermis, targeting INTERMEDIATE FILAMENTS; KERATINS; and filaggrin for CITRULLINATION to promote epidermal cornification.
