3.5.3.15 Peptidyl arginine deiminases (PADI)

Peptidyl arginine deiminases (PADs) are a family of enzymes that catalyze the conversion of arginine residues in proteins to citrulline residues through a process known as citrullination or deimination. This post-translational modification can affect the structure and function of proteins and is involved in a wide range of biological processes, including gene expression, apoptosis, and the immune response.
