Notes: Citrullination and carbamylation are two post-translational modifications that result in the generation of citrulline and homocitrulline, two highly related, non-standard amino acids. While citrullination of arginine is catalyzed by peptidylarginine deiminases (PADs), homocitrulline results from the non-enzymic reaction of cyanate with lysine. Carbamylation occurs at low levels in healthy individuals, but at higher levels in several clinical conditions such as atherosclerosis, kidney disease, and inflammation.{33133,33134,33135} Carbamylation can lead to changes in protein function, cellular function, and generation of an immune response to homocitrulline containing proteins.{33133,33134,33135} This product contains a carbamylated mixture of H1, H2A, H2B, H3, and H4 histones isolated from calf thymus.
