Nucleoside monophosphoramidate hydrolase from rat liver: purification and characterization
The International Journal of Biochemistry
|February 1, 1994
Abstract:
1. Adenosine 5'-phosphoramidate hydrolase of 29 kDa was isolated from rat liver cytosol. 2. It consisted of two subunits of 14 kDa. 3. It hydrolyzed nucleoside 5'-monophosphoramidates into nucleoside 5'-monophosphates and ammonia, while it did not hydrolyze adenylyl phosphoramidate, adenylyl imidodiphosphate and N-phosphorylated compounds like phosphocreatine, N omega-phosphoarginine, 6-phospholysine and 3-phosphohistidine. 4. Divalent cations and cyclic AMP had no effect on the hydrolytic activity.
