title: Human placental nucleoside kinase activities.
abstract: Our studies have indicated that normal human placental cytosol contains a complex mixture of nucleoside kinase enzymes, some of which conform to previously characterized activities. Deoxyadenosine is phosphorylated by deoxycytidine kinase, adenosine kinase, and two as yet uncharacterized activities. Deoxyguanosine phosphorylation is associated with deoxycytidine kinase. More complete and detailed studies will be necessary to characterize these enzymes fully.
