WebJan 25, 2024 · A less explored protein PTM, conversion of peptidylarginine to citrulline, is the subject of this review. The process of citrullination is catalysed by peptidylarginine deiminases (PADs), a family of conserved enzymes expressed in a variety of human tissues. Citrulline can be derived from: from arginine via nitric oxide synthase, as a byproduct of the production of nitric oxide for signaling purposesfrom ornithine through the breakdown of proline or glutamine/glutamatefrom asymmetric dimethylarginine via DDAH Citrulline is made from … See more The organic compound citrulline is an α-amino acid. Its name is derived from citrullus, the Latin word for watermelon. Although named and described by gastroenterologists since the late 19th century, it was first … See more Several proteins contain citrulline as a result of a post-translational modification. These citrulline residues are generated by a family of enzymes called peptidylarginine deiminases (PADs), which convert arginine into citrulline in a process called citrullination or … See more • Citrullinemia See more
