Quantitative analysis of modeled ATP hydrolysis in water by a colorimetric sensor array

Abstract

Self-assembled colorimetric sensors have been prepared from ZnII-DPA-attached phenylboronic acid (1·Zn) and catechol-type dyes. The 1·Zn-dye sensors display selectivity towards oligophosphate over monophosphates. The colorimetric sensor assay (1·Zn-dye) is utilized to monitor a model of a metabolic reaction where ATP is hydrolyzed to pyrophosphate (PPi) and AMP.
