Enzymes of adenosine metabolism in Hymenolepis diminuta (Cestoda)

Gaitanaki C. and Beis I. 1985. Enzymes of adenosine metabolism in Hymenolepis diminuta (Cestoda). International Journal for Parasitology15: 651–654. The activities of 5-nucleotidase (E.C. 3.1.3.5), adenosine deaminase (E.C. 3.5.4.4), adenosine kinase (E.C. 2.7.1.20), AMP deaminase (E.C. 3.5.4.6) and adenylate kinase (E.C. 2.7.4.3) were demonstrated in homogenates of Hymenolepis diminuta. The K_m values for adenosine and AMP of the above enzymes were determined. The importance of these enzymes in the maintenance of adenosine concentration on a steady state in H. diminuta is discussed
