Figure 1From: The Metal Coordination of sCD39 during ATP HydrolysisATP hydrolysis by sCD39 with VO2+ as cofactor analyzed by HPLC. 2 μg of sCD39 was included in each assay. A. The reaction was conducted in the presence of 0.5 mM ATP but without VO2+. B. The reaction was initiated by adding 0.5 mM VO2+-ATP (1:1). ATP is represented as black diamonds; ADP as a black square; and AMP as a black triangles;Back to article page
