Galactose-1-phosphate uridylyltransferase activity in chronic lymphocytic leukemia.
Galactose-1-phosphate uridylytransferase (E.C.2.7.12) activity was measured in both lymphoid and erythroid cells from patients with chronic lymphocytic leukemia (CLL). Decreased enzyme activity was found in both cell types using two assay methods. The results suggest the presence of an inhibitor of the enzyme in CLL patients. A correlation between decreased uridyl transferase activity and glycogen accumulation in CLL is postulated.更多
