Calcium 38-45 peptidyl arginine deiminase 4 Homo sapiens 94-122 23382808-5 2013 Asn153 and Asp176 are directly coordinated with Ca3 and indirectly coordinated with Ca5 via a water molecule. Water 94-99 carbonic anhydrase 5A Homo sapiens 84-87 23382808-7 2013 Asp168 is the direct ligand for Ca5, and Ca5 coordination by Glu252 is mediated by two water molecules. Water 87-92 carbonic anhydrase 5A Homo sapiens 41-44 23382808-11 2013 In addition, the results of urea-induced denaturation for the N153, D155, D157 and D179 series mutants further suggest that the binding of Ca(2+) ions in the N-terminal Ca(2+)-binding site stabilizes the overall conformational stability of PAD4.
