Figure 5From: Characterization of the interactions between the active site of a protein tyrosine kinase and a divalent metal activatorKinetic analysis of Asn319Ser. Double reciprocal plots of Asn319Ser, using ATP (A), kdSrc (B) or polyE4Y (C) as the variable substrate. For the determination in (A), polyE4Y is used as the phosphate-accepting substrate.Back to article page
