Abstract:
RATIONALE Related with its ability to degrade nucleotides, intestinal alkaline phosphatase (iAP) is an important participant in intestinal pH regulation and inflammatory processes. However, its activity has been investigated mainly by using artificial non-nucleotide substrates to enable the utilization of conventional colorimetric methods. To capture the degradation of the physiological nucleotide substrate of the enzyme along with arising intermediates and the final product, the enzymatic assa...     »
