Ca²⁺ independent generation of mono- and diphosphate nucleotides by LALP70v activity. Phosphatase products of LALP70v activity with ³H-UTP/UTP as substrate and in the presence of 500 μM Mg²⁺ and various concentration of Ca²⁺ were detected and analysed as described in the legend to Fig.2. Mean values from three separate measurements are given.
